Tin,
You're right about San Antonio being a major military, especially Air Force town. I have 3 brothers who are retired Air Force and I'm ex- army. So, guess what - reunions are often held in San Antonio. That suits me beacuase it's an interesting part of the world and for me, there's lots to do even outside of the model engine world. I'll try to check out the transportation museum and anything else that looks like it has flywheels, gears, or runs on steam ;D
Cheers,
Phil
