Folks, we know where the people who are destroying the Pines are going. We have a pretty good idea of when they're going back there. A far more effective way of deterring this sort of activity would be to increase the number of rangers back there - at all hours of the day and night - and enforce the laws.
Don't take away access to the woods because you're unwilling or unable to do your job. If you're not funded properly enough, then get all of these concerned citizens focused on lobbying Trenton for more funding, find grant money, or whatever it takes. But don't think that nailing up a few signs and calling it a day is even going to remotely make a bit of difference.
Sorry, but shame on the Wharton State Forest Police for this one. If folks had been out enforcing the rules years ago, Quarter Mile would not be the mess that it is now. Everyone involved can pat themselves on their backs and say that they're accomplishing something. Well, since everyone (even folks in the NJTLC) agree that the signs are going to be destroyed, then you're just wasting your time and nothing really will happen.
