Well Stig, your memories are pretty accurate for that period of time. Your post brought to mind many of the issues you discussed.
This is my hometown, and was back then. I have traveled many places, and countries, so I have seen other cities and their problems. They - we who make cities what they are - all have their problems. Or uniqueness.
I am proud and honored to say that I was a part of the changes that came to San Antonio since then. It is now a favorite city for veterans, and active duty. All the bases here now have much tighter security. The bicycle lane that I used to ride to cross Fort Sam is closed. Those old funky barracks looking houses around the base have been fixed up.
Traffic is still scary, however, I have found that to be the case in almost every city I have visited or lived in. Austin, San Francisco and Sacramento, and Davis are my personal favorites for scootin' and bicycling.
