Largest let down? Had tickets to Rush and the day of the concert my ride cancelled. I had had my license for three days and no way were my parents allowing me to drive to Hartford (sold the tickets at UMass, so at least I got my money back)
Tidbit: Turned down Pink Floyd at Foxboro as I really couldn't afford it at the time, so instead I stayed home and stepped on a piece of glass that bled all over my apartment.
