I ran across these postings and thought I would give my first hand experience. BTW, I am also from San Antone- born and raised
My wife, son and I moved to Ft Mac from the UK. The previous poster was correct, the grounds on Ft Mac are very nicely maintained and all of the amenities of a base are located on the base (minus the gas station and commisary)
I think it is a good way to transition to this area. It alleviates the hassle of finding after hours child care and other issues related to PCSing to a new area.
The base housing is now contracted out to a management company and are called Tierra Vista? We moved out just as the transfer took place. We moved only because the location itself is not very convenient. My wife works in Santa Monica and the commute on the 405 freeway to San Pedro was horrendous! Anyhow, we now live in Culver City, a nice suburb between Santa Monica and San Pedro. You do have to make some sacrifices to live in the community and keep it within an affordable range. Townhouse style apartments seem to be the smartest way to go without exceeding the housing allowance by too much. But you do sacifice a yard and if you have more than one child this may be difficult.
San Pedro itself is not the nicest area, but we didn't really do too much in that area when we lived there...probably for that reason.
Hope this info helps on your decision.
