Past Magic Vally, take the salem loop, and get to tanner hill road. Then you should see a driveway with a sign that says "Insane Paintball"
This feild is awsome. I have played at other(s) but this one is sweet. It has a great location, super friendly staff, and good prices. The rental guns are good too.
The woods ball course is unbelievable! Lots of bunkers and objects to hide behind. All home-made too. Well constructed by the owner.
I went for a walk through of the upgraded course yesterday and there are plenty of inprovements for this season/year and more to come. Its just a sweet place to play, and the staff are friendly and they make you feel at home.
I highly recomend that you go to this course and give it a try!
