I saw the speedball field but it seemed a little trashy, hard ground, old bunkers.. Though the recball field was awesome! They constructed a 40X40' fortress in the middle of it all with close quarters and 4 towers on each corner. Also there's a flag to raise for people wanting ultimate role playing. Plenty of obstacles outside the fortress ranging form wood crates to plastic barrels to tire bunkers to cars! The field is probably the size of a football field so there's plenty of room to get around 40-50 players. I went with 6 other buddies and had all out war! We played Attack and Defend and really used the fortress to it's purpose. If you've never played with a building to attack, give this place a shot - it really makes for new elements of play. The staff was pretty nice, answering all our questions and chatting away. It's very cheap - $20.00 for entry and air (byop or buy their's) - you can even ask to swap your CO2 for HPA or HPA for CO2 - they don't mind at all! If you want to modify your weapon with a HALO Hopper or add a barrel, they'll let you do that as well! It's the best field I've played at and with the ability to use their equipment for no charge, it definitely adds plus' to their place. I give it a 10 because the recball field is totally awesome and gives room for many players and many game styles. The staff couldn't help more with mods and assistance. My buddies hopper went to crap and they let him use an even better one! No refs so you can have as much fun as you want. I'll be going there next weekend with my own paint and only 20 bucks!
The Rec field is larger than a football field. I think its probably 400x200. I work and play the rec field a lot, so hit up the guy with the Black Grillz and Blue Empire gear next time you're out there.
