I started sitting in the 500s behind homeplate last year, and I love those seats. Plus they have those vendors with 50+ different beers.
Favorite game i've ever been to at the RC has to be the wildcard game. 500s behind home plate, dome open, wearing a sweater, watching that walkoff... Damn.
Anyways, I love the 500s on summer nights. You get the nice breeze up there. Its great. Plus the seats are cheap as f***.
