Went to Def Leppard, Styx and Tesla concert last night and the bands were AWESOME. The problem we had was after the concert getting out of the this hell hold. We were parked all the way in the back at row F13 and figured being there we would be the first ones out. It took us over 1 hour and 1/2 to get out of the parking lot! Very poorly organization on directing people out. We have been to tons of concert and this was by far the worst when it came to leaving the parking lot.
