So far here are the ballparks I have been to:
Hubert Humphrey Metrodome
This year I want to try to get back to Minneapolis to see the new Target Field, Coors Field, Yankee Stadium, Citi Field and Camden Yards. I'm not too familiar with the Denver area, so if anyone has any suggestions on where to stay and what else to do, let me know. I plan to make a weekend out of it.
