I had been shooting near there about 4 years ago, very nice area but I choose not to pursue it due to the heavy traffic there. Many people bike and 4 wheel in the area and everytime I went there, there were always paintballers roaming the woods. One day, I was hiking in the area first and approached some paintballlers who had just arrived. I was exploring the place and told them I would only be 15 mins as they were just setting up anyways. I also told them where I would be hiking at and they said that was fine, they would wait. Well not more than 5 mins later I heard paintball discharges through out the woods and when I returned to my truck I had found they had shot 6 rounds of pink paint onto my truck. Well I was pissed to say the least, but kept my cool and proceeded to start my truck up to leave when they shot it again while I was in the truck! The guy I was with had to calm me down a bit and I ended up giving them a Sinjin Salute and rode off. It is a very popular paint ball area and I didnt want to have our people drive all that way to deal with crap.
Last time I was there, 5 months ago, they had put up a sign at the entrance to the spill way saying No Trespassing, shooting, off roading, or hiking. This is the main entrence to that wooded area and unless they changed their mind I think it is probally the same. The sign still didnt prevent people from shooting there as they disregaurded it and shot anyways. But a few check ups by the authorities and Im sure people will start to move else where. I would definately make sure that the access to the area, ie spill way, and the area its self are ok. But I wouldn't hold my breath, if it were still ok, you still have to deal with the paintballers. And the fact is, the field is simply not large enough to share between two groups.
