I'm a bit surprised that Progressive is ranked so low, the first real shocker of the rankings.
I haven't been to as many as Pedro but mine would be:
1)AT&T
2)PNC
3)Camden Yards
4)Coors Field
5)Safeco
6)Fenway (haven't been since the renovations)
7)Progressive
8)Yankee Stadium
9)Rogers Centre
10)Nats Park
11)US Cell
I've also been to these "deceased" ones: "Old" Yankee Stadium, Veterans, RFK, Olympic, Tiger Stadium, Riverfront, Three Rivers, Qualcomm, Candlestick, and Memorial.
I've been to Wrigleyville but unfortunately the Cubs weren't playing either time I was in Chicago -- one of those times was in October for my cousin's wedding, but you knew the Cubs wouldn't be playing.
