STYX 1973, Mcdonald Arena, SMSU Campus, Springfield, Mo. I was 12 yrs old, had floor seats with a buddy and took a hit off of every joint that was passed to me.
The first time the guy next to me turned to pass a joint he stopped, gave me the eye, shrugged and gave it to me.
Good thing I only lived about a block away. I was high as a kite by the time the concert was over.
