The ones I have been to: Oakland Coliseum, Truist Park, Fenway, Wrigley, Coors Field, Angel Stadium, Dodger Stadium, Target Field, new Yankee Stadium, Citizens Bank Park, Oracle Park, National Park, Globe Life Field, Ballpark at Arlington, Arlington Stadium
The ones I haven't been to yet in order of interest: Petco Park, T-Mobile Park, PNC Park, Oriole Park, Kauffman Stadium, Great American Ball Park, Progressive Field, Comerica Park, Astros ballpark, American Family Field, Citi Field, Busch Stadium, Rogers Centre, Chase Field, Rate Field, Chase Field, loanDepot Park
mdleast figures we can try for the Astros some weekend in the future since it's just 4 hours down the road. Kauffman can be a quick trip since it's a short flight. I'd group the Ohio teams and Pittsburgh as a long weekend to make it worth the airfare. Detroit and Toronto could be the same weekend since it's a 4 hour drive. Milwaukee and White Sox can be the same weekend for the same reason but I would have to see about a Wrigley visit again. I've been 4 times already. I figure we could squeeze a Baltimore-Mets double into one weekend if we flew into one, took the Amtrak to the other, and then flew out of that city. We did that on the disastrous Maryland game weekend at FedEx. Flew into DC, Nationals game, watched the Herman abortion, took the train to Philly to watch the Phillies, and flew out the next day. Baltimore was out of town that weekend as that was much more preferred and just under an hour away from DC. Arizona, Miami, St Louis would have to be one off trips and therefore rank the lowest.
