I am presently going through the process of gaining a handicapped permit for pretty much everywhere they are available, State Parks, State Game Lands, and now, State Forests. While the State Parks and Game Lands are permitted to allow use on any of them with only one permit for Parks, one for Game Lands, the State Forest Handicap permit is good only for the Forest designated on the permit. There is one thing else which is universal for the handicap using a permit, that being you ARE allowed to bring a person along who may assist in the trailering/ unloading of the vehicle being used for the hunt, and may also accompany the permitee to assist if necesary to the safety and/or well being of the hunter.
For example: you have problems trailering, or getting on or off the ATV, even if not necesary every time, you CAN have someone to aid you as necesary. If this person is also a hunting partner that's fine too.
I hope this clears up some question for some, I know it was perplexing for me at first. Oh.....Blaze orange rules also apply whether the "helper" is hunting or not.
