If I'm breaking rules then pull this please.

I've seen a few people ask about seats in certian stadiums and sections. I've been using a site called  http://www.seatdata.com/ . It's totaly free so this isn't a plug. You can pick MLB NFL NHL NBA stadiums and arenas or choose by team. You click on the venue then click on your section to see a view. It really is helpful so I suggest it for 1st time trips to stadiums before purchasing tickets. For instance...you want to sit in section 209 at Wrigley but not sure if your view will be blocked...

Now if you want lager images you have to pay but otherwise it's free to use for the small images and very helpful.
