I think in the next 5 yrs you will see multiple satellite bases. As mentioned, the day/time of brick and mortar bases is passed. There is really no reason to ever go to the crew base. The only reason I go down is to check my mailbox, which is pretty useless.
Zero reason. I email or call if I need to speak to a chief, and that is seldom. They could be in DAL for that matter.
MCI, STL, SAN, AUS, SAN, TPA, SMF, SAT could all be virtual bases. We don’t use reserves traditionally anyway, so not an issue there.
