So who has been to games at the most stadiums (major league only)?
here's my list:
1. Shea, NYM
2. Camden Yards, BAL
3. Nats Park (and RFK)
4. Turner field (the new one), ATL
5. Chase Field, AZ
6. Miller Park, MIL
7. U.S. Cellular Field, CWS
8. Petco, SDP
9. AT&T Park, SFG
10. Fenway Park
AT&T was probably my favorite, just for the look/feel and experience, though it was freaking cold (40's). Petco and Miller were really nice as well. The Diamondbacks stadium is wondeful, but I've been to 3 games there and unless you are lucky enough to sit near a transplanted east coaster, you'll find people with no clue as to what's going on on the field.
I'm planning on visiting the new Marlins stadium in August.
