We visited Nationals Park for the Brewers' series in April 2010 (featuring the Counsell Grand Crush). The park isn't ultra distinctive, but I liked it. That series drew only 15K-17K per game, and we didn't feel even particularly in the minority wearing Brewers gear. One thing I enjoy about the postseason is when a team that hasn't had a chance in a while (or ever) gets a turn, and their park fills up and gets enthusiastic, and some fanbase other than NYY or STL gets a thrill. So I'd probably be rooting for the Nats tonight even if they were playing someone else.
