go rt 80 to exit 19 Hackettstown Allamuchy. At the light make a left onto 517 and go a mile or two till you see Mattar's Restaurant on the right. Make the next left onto deer park road. (look for brown sign on right). You can also come down 46 west in Hackettstown and make a right onto 517 at the Hackettstown trading post (across from Marty's bikes) go like three miles or so till you make a left onto deer park road. If you see Mattar's on left you juuuust missed the right. Go to the first parking lot.
