Are you looking for a nice quite place near San Antonio?
There is a fairly new subdivision very close to Randolph Air Force Base in Converse, Texas called Miramar. This might just be the place you have been looking for to get out of the traffic that comes with the big city. There are still a few Homes in Miramar but new construction is just about finished.
Many of the residents are active military or retired military so the population tends to be quite pleasant. Miramar might be worth looking at if you are looking for a home.
