When I was 14 in the short camp break between being a camper and staying on as a Jr. Counselor, an older Counselor took me to the now gone Armadillo World Headquarters in Austin. There, on a picnic bench style beer table was a couple going at it during the concert. Bang a song, indeed.
Junior year in high school. Me and the girl who shall remain nameless snuck onto the 14th green at this place at night with a blanket, some herbiceuticals and went at it like wildcats.
