The area is access sensitive!
PARKING! Parking is only allowed on the grass field marked on the map. Turn your car 90 degrees from the dirt road and drive onto the field, so that as many cars as possible can park (back or front of the car facing the dirt road). Don't drive further onto the field than necessary. Start parking from top to bottom. Leave as little space as possible between each car. If parking is full - go to another sector.
SHITTING! If you can't hold it anymore, go really far into the woods, dig a hole (with your hands if necessary), and fill the hole up after your done. Leave no trace!
