The owner and his staff are the best I've found at any field and they are all about customer service. I was almost ready to quit Paintball completely due to some bad experiences at other fields and my buddy convinced me to go to GTF and I haven't been anywhere else since and I play twice as often as I used too.
The field are great quality with speedball, woodsball, and scenario fields(3). My favorite field is the DEA house!! They just opened this up and I love the fast play and the tight spaces, my heart races the whole game. You can't find this kind of play other places.
The people there are great. Every time I go I see ballers helping each other out with marker problems, etc., and discussing strategies/gameplay. They have a great scenario team that is homebased there called Firecomm 1 who I see helping out all the time either with fields or with peoples equipment problems and they really add to the great experience.
