Will be going to a game at Fenway Park this year. Living in CT gives me a lot of chances to go and with it being the 100th anniversary, its a must. Will also go to a few games at Citi Field (my favorite of the 2 in NY) and probably a game at Corporate World (Yankee Stadium). As much as I like the stadium, its too expensive and too flash.
I am heading to FL in June and will be going to a Red Sox @ Marlins game for the new Stadium. I am down to 9 stadiums remaining. But have them paired up for trips (St L - KC, Arlington - Houston, Phoenix - Denver and Cleveland - Minneapolis).
Will also be going to a Dodgers @ Nationals (Sept 20) and Brewers @ Nationals (Sept 21) games. I really like Nationals Park and tend to go there every year when I trek down to DC.
