The only thing that works is having the State Police arrest them for trespassing. This must be done by the land owner. An eye witness can get info and testify if needed that said person was seen on the property. But the land owner needs to prosecute! But it only takes nailing one or two people before the word spreads and people get it!! Unfortunately people don't have any respect anymore and the only thing that works is nailing them when they are caught.[:@]
