I am not an authority on the subject. However, I think the problem is keeping the rangers or land mgrs. aware of exactly who is supposed to be maintaining the trail and who is altering it for their own good. Currently, SWAMP has scheduled maint. days, so everyone knows if someone is doing something during a different time, it probably is not "OKed" by SWAMP. I know there is a lot more to it, but I think that is the gist.
