I have several buds who retired out of RND and intended to stay living in San Antonio while they commuted to their jobs at legacies (including guys who were at UA in IAH and AA in DFW).
Within 2 years, about 3/4 of them had moved from SAT into base. Given the large number of USAF retirees in the San Antonio area, apparently the jumpseats can be tough to get. They had to make the drive a few too many times...
