My experiences at Yankee Stadium: Bleachers are cheapest. Don't be fooled by the fact there is no alcohol served. The fans out there still act like @sses. As goony/jersey said, the upper deck is very steep and narrow. You trip, you're falling all the way down. The atmosphere is pretty decent though, if you can ignore the more obnoxious fans. I've been to Shea once for a game against the Cubs about 6-7 years ago and it was bad. Planes were flying overhead every 5 minues, so you couldn't hear yourself think. Seats were garbage. Fans were obnoxious to the extreme. This old lady behind us with this annoyingly whiny voice was bad mouthing the Cubs all game and had an unhealthy obsession with Desi Relaford, to the point where she called him "her Desi".
