I played there last weekend with a couple friends. Had a lot of fun. They just built two new fields, one being the new speedball field, which is made of big hay bails, great for like 3v3's or 5v5's. They just built this new urban combat field too which looks very cool. Its a huge field with pretty much an entire realistic town in it. I think they are still building it but its got two towers up so far that are gona be connected. They also redid the back woodsball field and the castle since the last time I was there.
Prices: Prices have come down a LOT. Its only 15 dollars a bag now and 10 dollar entry, but if you go there within the first hour that they are open its half price admission! A rental package is 10 dollars, or 15 dollars if you want the upgraded package (better gun I think).
Their refs are real nice and are very helpful. It was kinda busy on Saturday but they still kept the games going consistently throughout the day. Their pro shop is kinda small, but dan said they were planning on opening a new retail store soon. They still have a lot of stuff though, and just about any part you need if your gun needs repair.
Conclusion: Great field! super friendly staff, very nice fields, just make sure you get there within the first hour that they are open for half price admission!
