also, there is a significant difference in sound between the many sections of a venue...to think otherwise is foolish
sometimes I will gladly abandon excellent seats due to a negative vibes or just being too squeezed (even if there isn't a stub-down crowd). I had something like 10th row at LA Greek last year & found the spacing of the seats to be just too tight for my liking ... didn't help matters that the guy next to me kept leaning over & talking to the guy in front of me who he happened to know. Part of me didn't want to "give in" and let this joker get more space, but wasn't worth it to me to start up ... so I drifted back to the first crosswalk and was able to groove the rest of the show there, right behind the sound board. There was a big plywood wall, but I could see over it and the sound was actually better.
