Like 12? Don't remember exactly.
A two nighter in DC in 2000.
My friend and I followed them deadhead style for several shows in 2003:
Pittsburgh, Lexington (or was it Louisville?) KY, st louis, indianapolis, ohio (columbus for sure but maybe Cincinnati and Cleveland too?)
Then other times:
Chicago, Asheville NC, and the first No Fun Fest with Thurston and Paul Flaherty, and Kim with dj olive, ikue mori, and jim o'rourke.
I think I'm forgetting some. I think columbus again? I know I saw a sonic nurse show.
