If you decide to stop and have a picnic, camp, or go hiking, you need a State Land rec permit for you to do that recreation. If you stage on State Trust Land, the vehicle you leave behind needs to have a permit hanging in the window, so that means you have to buy a permit for your tow vehicle in that case.
Thanks for the correction Jeff. I was thinking of "access" being more like staging, camping, and generally hanging out and riding.
