Arena/shed shows are so unappealing for me these days...and getting really cheap seats is kind of worthless.. you're so far away and can't see anything and the sound is crap...the only way shows in those venues can be worthwhile is if you have a really nice seat.. otherwise you might as well not go...
I saw the Rolling Stones in 1997 or so at then Jack Kent Cooke Stadium from the worst seats in the place (Sidehatch procured seats of course) and it turned me off to them for years....then in 2006 a friend reeled me in and I saw them in Baltimore and was relatively close and it was the best show ever.....
