Maine has a good swing for a pitcher but on anything that moves, he has no chance. And if it's a fastball, it has to be up in the zone. Basically, the pitcher has to hit his bat. - Mike Pelfrey

I could figure out just about all of them just by looking through the first time. The two domes were the only ones that gave me trouble to start with, but I sorted those out pretty quick. I knew that road trip would pay off sooner or later in some useless knowledge competition.
There...I've knocked out the two hardest ones...now you guys get the rest.
That one was easy.
RFK is the football stadium
Yeah, Camden Yards is easy to spot with the B&O warehouse which is the longest building on the East Coast or something equally ridiculous. Anyway, I end up there about a dozen times a year since it's about 45 minutes away.
