You were there about the same time as myself.
I was statiooned at Fort Sam Houston to go through Medic school, and went down for a look around. Brothels and Mexican goods for sale. The beer was cheap and the women were too. They actually made us pretty welcome, they recognised young horny guys with money to spend. Biggest problem was shaking off the shoe shine kids.
I'll never forget how beautiful some of the Mexican girls were.
Also beautiful was the Mexican music.
