       Summary of the Proxy Statement/Prospectus, page 28

   1.                                                   We note your amended
disclosure on page 32 regarding the Sponsor, Thayer's directors
                                                        and officers and their
affiliates participating in the PIPE transaction. Please revise your
                                                        amended disclosure to
state, as indicated in your response, that there are no material
                                                        differences in the
terms and price of securities issued at the time of the IPO as compared
                                                        to the private
placements contemplated at the time of the business combination.
   2.                                                   We note your response
to comments 9 and 10 and reissue the comments in part. Please
                                                        revise to explain
whether your structure is unusual compared to other mergers and initial
                                                        business combinations
by SPACs and (1) clarify the extent to which the combined
                                                        company could otherwise
receive tax benefits instead of providing them to members who

         "continue to realize tax benefits" and realize other benefits in the
future under the TRA,
         and (2) identify the members receiving the tax benefits with as much
specificity as
         practicable.
Risk Factors, page 52

3.       We note your amended disclosure on pages 83, 89 and 99 regarding the
sources and extent
         of dilution that non-redeeming shareholders could possibly experience.
On page 83 you
         note that shareholders may experience further dilution from the
exercise of options and
         warrants that would total 23,254,000 shares of Combined Company Class
A Common
         Stock. Yet, on pages 89 and 99 you disclose that the same exercise of
options and
         warrants would total 23,353,734 shares of Combined Company Class A
Common Stock.
         Please reconcile this conflicting disclosure regarding shareholder
dilution.
Proposals to be Considered by Thayer's Stockholders, page 126

4.       We note your revised Background disclosure and responses to comments
14 and 15.
         Please revise to clarify why you discuss Party A but none of the other
14 potential
         candidates who signed non-disclosure agreements. We note the statement
that the parties
         determined it would be in the best interests of stakeholders "to
implement a customary
         UP-C structure." Please revise to address negotiations about whether
or not to implement
         an UP-C structure, customary or otherwise. Additionally, disclose the
range of values in
         Thayer's comparable companies and other analyses prepared with the
assistance of
         Evercore, and summarize on page 130 in quantitative terms the
differences between the
         original and updated projections with the more detailed data presented
on page 137.
5.       We note your response to comment 17 and amended disclosure on page 130
that the
         presentations given to PIPE investors were materially similar to the
information contained
         within this prospectus. However, we note in your amended disclosure
that the PIPE
         investors were provided with updated projections, which do not appear
to be reflected
         in the amended disclosure. Please revise your projections disclosure
to include the set of
         updated projections that was provided to PIPE investors.
6.       We note your response to comment 18 and amended disclosure on pages
137 and 138
         regarding the basis for the assumptions that underlie the Inspirato
financial projection
         numbers for the next five years. Where you address assumed increases
or decreases in
         revenues and costs, please revise to clarify when and to what degree
the rates of increase
         or decrease differ from prior periods. For example only, clarify these
assumptions when
         you address the growth of the residence portfolio, increase in nightly
room rates paid by
         subscribers and increases in nights traveled by subscribers.
Projections, page 137

7.       We note your response to comment 22 and your revised disclosure
beginning on page
         137. We also note the historical measure of revenue growth and
compounded annual
         growth rate of revenues comparing 2012 to 2019. To provide context,
please provide

         additional disclosure comparing your projected revenue to your
historic operating trends,
         focusing on more recent trend information, even if prior to 2020.
Please discuss why any
         change in trends is appropriate and why your assumptions are
reasonable. Your
         disclosure should clearly describe the basis for projecting your
revenue growth and the
         factors or contingencies that would affect such growth ultimately
materializing.
The Business Combination Agreement, page 141

8.       In the table on page 145 revise to include approximate share ownership
percentages and,
         where applicable, voting control.
Material US Federal Income Tax Considerations, page 163

9.       We note your response to comment 23. Please explain for us whether the
transaction
         is intended to constitute a reorganization within the meaning of
section 368(a) of the
         Code.
Information about Inspirato, page 197

10.      We note your response to comment 25 and reissue the comment. Revise
page 212 to
         clarify how TAM can represent your potential market when SAM already
quantifies the
         market for the future supply to include on the Inspirato platform
based on its current
         business model.
11.      Please reconcile the statement on page 217 that Inspirato has
approximately 590
         employees with the statement during the November 3, 2021 Inspirato
management
         interview that it has over 700 employees. Additionally, please revise
MD&A to address
         the statements surrounding the plan to establish a warehouse facility
and pay for $100
         to "$150 million of inventory."

Results of
Operations, page 234

12.      We note your response to comment 28 and revised disclosure on page
237. Please revise
         to quantify the "significantly lower" subscription revenues compared
to ARR.
         Additionally, please reconcile the statement that "ARR does not have a
standardized
         meaning and therefore may not be comparable to similarly titled
measures" with the
         comparative chart and detailed figures on page 25 of the slides
included as Exhibit 99.2
         with the Form 8-K filed on June 30, 2021.
Information About Thayer, page 251

13.      We note your amended disclosure on page 255 that the Sponsor and
Thayer's directors and
         officers will not be reimbursed for any out-of-pocket expenses
incurred in pursuing a
         target for an initial business combination. Please reconcile this
disclosure with the
         statement on page 255 that the audit committee will conduct a
quarterly review of whether
         or not to reimburse the Sponsor or Thayer directors and officers in
connection with their

         out-of-pocket expenses incurred in the pursuit of an initial business
combination. As it
         appears that expenses could be reimbursed under certain circumstances,
please revise here
         and the third bullet point on page 24 to quantify the amount of
expenses that have been
         incurred as of the most recent practicable date.
Management after the Business Combination, page 268

14.      We reissue comment 36. Please revise to identify the initial members
of the 5-person
         board of managers and clarify their role as compared to the roles of
the executive officers
         and directors.
