On Constitution, about 15-20 min away from route 3, and right by Locust Grove Elementary (I think) school.
I was part of a private party that reserved the field for a day, we consisted almost entirely of noobs (myself included), and we had an excellent time. Tor was great, he answered all of our questions and it was clear that making sure that our group had a good time was his top priority. He brought two experienced paintballers on to act as guides for each of our teams, and it was really nice having a person on each team who new the fields and could offer advice and suggest strategies. It worked very well. Additionally the ref was fair and friendly and was able to quickly resolve any disputes.
The fields were awesome. They had a two story fort/tower, 2 bridges (one of which was massive), a guard bunker, loads of various forms of cover (everything from stacked brush to aluminum walls, to a very well done wooden fence complete with ports that circled the fort), and various paths. The fields played very well, we played two and they each felt very distinct. They were set up well and felt very balanced. Some game forms combined multiple fields together, and Tor said that they hoped to have a speedball field completed by the end of this summer.
Pricing was excellent as well, $35 covered walk on, rentals, and all day air. And the rental equipment was very nice as well, the masks did not fog and the guns were tippmann's fitted with response triggers.
I had a lot of fun and I believe that everyone else did as well. Warplay comes highly recommended, I gave it a 10 out of 10.
