There are no rules or regulations for camping on Success Pond road as it is all private timberland owners. Note, if you elect to have a fire, you will need a permit and I believe that you have to have the owners permission.
Obviously you should stay away from active logging operations, not block roads and practice carry in carry out. Be aware that there is a party crowd that on occasion visits the area at night, shouldnt be a problem if you are well off the road but you may have some "guests" who drop by.
In the past there have been problems with car break ins and vandalism to cars that were parked long term, but it seems t have slowed down.
