I've been to more parks than most people I know, but I still have quite a lot to see a game at!
I have been to a game(s) at the following:
Astrodome- Houston Astros
Minute Maid Park- Houston Astros
Turner Field- Atlanta Braves
Ballpark at Arlington- Texas Rangers
McAfee Coliseum- Oakland Athletics
Safeco Field- Seattle Mariners
U.S. Cellular Field- Chicago White Sox
Comerica Park- Detroit Tigers
On vacations I have seen these, but not gone to a game:
AT&T Park- San Francisco Giants
Wrigley Field- Chicago Cubs
Fulton-County Stadium- Atlanta Braves
Tiger Stadium- Detroit Tigers (sadly, it was being demolished at the time)
Citi Field- New York Mets
As of right now, I really would like to go to-
1. Citizen's Bank Park- Philly
2. Fenway Park- Boston
3. Great American Ballpark- Cincinnati
4. Oriole Park at Camden Yards- Baltimore
5. Citi Field- New York
Hopefully we'll be visiting new parks starting back in the 2010 season.
As for this summer, I'll have to "settle" for six games at Minute Maid in Houston. The first three games (series) are verses my favorite AL Team, the Tigers. Labor Day weekend, we'll head back to see the Astros and Phillies for the whole series as well. Looking forward to seeing my favorite player and 2008 WS Champion, Chad Durbin pitch there!
