My teams:
Citi Field - echo above comments, especially when compared to Shea!
Rentschler Field - very nice, very accessible, very NOT ON CAMPUS (argh, but wouldn't be accessible if it were). A little small, but room to grow (believe foundation is in place for an expansion to 55k when needed).
Gampel Pavilion - love it, but too small. Was built when we weren't sure a 10k arena would work for UConn. Typical short-sighted CT BS.
XL Center (Hartford Civic Center) - a morgue. a dump. hate it.
Other area arenas:
MSG - probably in the minority here, but I HATE this place. Don't get me wrong, going to the Big East Tourney there is a great trip, but this place is a dump. That, and one of the architectural gems of NYC (the original Penn Station - look it up!) was torn down to build it. All of the BS about it being the mecca of anything, or even somewhat historic, is crap. It was built in the 60's, for crying out loud! Also, add the scummy ownership, and it's a trifecta of suck. Oh, the Rangers suck, too
Giants Stadium - about to be replaced.
New Giants Stadium - should have been in Manhattan, but see comments on scummy MSG ownership, plus multitude of NY politicians on the take. No roof, either, thanks to crooked unions and inflated costs.
Biggest dump in the area, though - easy - Nassau Coliseum, home of the Islanders. Wow, what a pit that place is.
