Ever notice that starting about section 531 and then continuing onward to 532,533 and up, that the seats are usually empty? That’s because fans buy “cheap” tickets up there and stay on the concourse and never go to their seats because the sightless up there are horrible. I’m in Denver right now and last night I went to the Mets/Rockies game at Coor’s Field and I have to say they have a cool idea with the Rooftop. The Rockies tore out a bunch of seats and put in deck with restaurants and bars. Mostly you can stand and watch the game but there are General Admission seats in three sections that you can sit in also. This place got packed last night. The ticket cost $15 plus fees but you got back $6 that you could use towards food or merchandise.
