we did this before I think I have seen 15 or 16. Maybe more, counting football stadiums and stadiums that now dont exist is is in the high 20s maybe over 30 now.
But in that north east corridor you can hit a ton of them. I grew up in Maine and dated a stewardess in Cleveland and we drove and flew all over the place back then. So you can hit 10 up there without even trying.
Fenway Park numerous times.
Shea Stadium
Old veterans Stadium in Philly(saw Willie Mays when the Giants were in town back in 1969)
Detroit Stadium
Busch Memorial Stadium(old stadium numerous times)
Three ball parks and they are as follows.......Twins (Metrodome). Royals. Padres. Out of those three you can pretty much guess of who I think has the best ball park. Visited Petco Park twice....Awesome town, Great Ball Park, Outragious Mexican food (and great BBQ in the same restaurant where they filmed a scene from 'Top Gun'). With a little research on google you can find these places. I don't get paid enough from the sponsors to post here. LOL
