March 18, 1978 Corporate Rock Fest in Southern California

California Jam 2 was a huge success monetarily and musically.  I went with several friends, lost track of all but one, listened to some music, partied for 24 hours and, while trying to hitchhike out of the parking lot the next morning, got picked up by my friends I had lost during the concert.  The only act I didn't like at all was Ted Nugent.....although his fans were passionate!
