There is a fairly decent field located just north of Harrisburg off of route...322, called Linglestown paintball, I think it use to be called foxhole. it has decent woodsball fields but no airball. Last time i was there, which was, about 9 months ago, their prices were pretty reasonable. 15$ for green fees and all day air (CO2 or HPA). Paint was 55$ a case (Stinger brand). The field is a little difficult to find because you have to take a turn off the main road and drive past a cemetery, small housing development and a farm. They do have a pro shop however it is located back on the main road about a mile or two from the field the address is...
5974 Linglestown Road,
Linglestown, Pennsylvania 17112
. This was the field i started at , and it was such a good experience i have never stopped, i definitely suggest looking into it. and you can call the pro shop at 717-541-8323
though it dose keep weird hours (4pm to 8pm) because the owner runs the business on the side of whatever work he does for a living.
