If you're going down the right road you'll have to cross train tracks and right past the train tracks there's a HUGE building...That's the one, then turn and you should see a metal door a little ways down.
I've been there a total of two times and it was great!!!! The bunkers are fully filled(except for the occasional one that's kinda deflated), and the people are all cool. I haven't played rec ball yet because I'm a huge speedball fan. So I've played on Thursdays during the team practice nights. It's pretty fun but I not really good compared to their team that plays there(I mean a Tippmann A-5 vs. Shockers and DM's is kinda one sided) but it's still fun. The only thing I wish is that they had speedball on the weekend, because the last two times I played there I was on summer vacation. But now I have school and to have a 45 minute drive to get there and have it start pretty late in the day(not sure I think it started around 7 or 8) I haven't been able to play. So overall it's great, I'm planning on going to play recball sometime soon, and I have a cousin who goes there to play and he says recball's fun. So if you're looking for a challenge go and play on team nights, but if you're a beginner or just wanna have fun go play recball.
I would have given it a 10 if there was speedball on weekends.
