if you have less than average seats, do yourself a favor, and walk around the stadium behind home plate for part of the game. The view is open as you walk along the concourse, so you can stand anywhere and watch... right behind home plate even... great stuff!
Also, take a walk down the stairs in left field and you can stand a couple feet away from the pitchers warming up in the pen. Grab an Ichiroll while you're down there... hehe...
I live in Maryland and try to get home once a summer to see the M's in Safeco... my fav place to see a ball game, but then I'm a bit biased
