I am looking for a paintball site close to Philadelphia that isn't too expensive. 
By close to Philadelphia, I mean up to an hour and a half driving
distance outside Center City.
In terms of price, I'm looking to pay less than $30 per person (also
bear in mind prices of canisters and paintball refills).
Around 60 people will be attending, and we're looking to go during the
first week of September (or 2 weeks, at a stretch).
Thanks so much for your help! :)
