It's kind of depressing that MLB has been to Target Field and I haven't.
Well then, just go there, and you won't be depressed anymore!
It really is a very nice ballpark. Much better than the Metrodome. It'll even get the All-Star Game next year!
As for my trips this year - probably the ones I'm most excited about are AT&T Park (Giants) and Dodger Stadium. Those will probably become my favorite non-NY parks by the time I get there!
