It was 1969, I believe. I was a freshman at Ga.Tech and had a friend going to Mercer in Macon, Ga. Led Zep was playing there (of all places) and I believe the venue was some auditorium on campus but maybe it was somewhere else in Macon. Anyway, I rode my motorcycle up there and stayed with my friend. They were promoting Zeppelin 2, it had just come out. LZ hadn't really "made it" yet and put on a terrific show. Later that year or maybe the next it cost me $1 to see the Allman Bros. and Janis Joplin on the GT campus.
