Doug, love these stories! I'm a little younger (49) so I missed the early 80's stuff live. Also I was broke as hell during high school so just went to parties and local clubs when I could roadie for friends bands and get in for free. Didn't start going to lots of bigger shows until the early 90's.
I just recently realized that the first time I saw Slayer was the San Berdo show that they recorded for Decade of Aggression. Only took me almost 30 years to figure that out!
