Thanks for the pack info.
As far as paintball in or around SF, it is practically unexistant, believe it or not. There is only one paintball shop located in SF, and they've made fun of me for having a Timmy (the joke's on them). The three nearest places to play are:
Sherwood Forest (I'll be there on Saturday) - http://www.paintballforest.com
Sunol - http://www.SunolPaintball.com
Paintball Jungle - http://www.paintballjungle.com
I highly recommend Sherwood and Sunol. I've never been to Paintball Jungle, and unfortunately, I haven't heard many good things about the place. Either way, you're gonna have to drive at least a half hour / forty-five minutes. No indoor fields that I know of nearby.
