GAB isn't on any of these lists...Busch Stadium is on one of them.
I'm not going to include Busch Stadium in my ranks because it's my home park so yeah, I love it.
I've been to US Cellular (White Sox), Wrigley (Cubs), Kauffman (Royals), Coliseum (A's), and AT&T (Giants). I'd rank them:
Kauffman, AT&T, Wrigley, US Cellular and Coliseum.
