I went to a Frank Zappa concert in 1974, San Diego. I was 17 years old.
My buddies and I decided to each by a "hit" of Strawberry Barrel (LSD)
What a huge mistake, I sat on a concrete floor for hours with my head buried in my lap.
I couldn't even come close to watching the show

We even had a designated driver in those days

The "high" lasted for 12 hours, it sucked, never did that evil drug again
