Several comment but first to Bones. No, the snow does not close a road. There is a blurb somewhere by the DNR that "temporary" acts of God, mother nature or something do not close a road. We had a copy of this letter several years ago and it is in the GLFWDA archives. It has been asked for by many of us to the person who has the archives but it has yet to be found.
Regarding the ORV routes, I am not up on the specifics of DI as some things have changed but if you hang your hat on the ORV route tactic, the route must be posted with the orange confidence markers. Are they?
JohnnyJ commented further up about shale beach and he knows it better than I.
Quite frankly, it appears that there has been quite a bit of lenience on DI with the rutted roads, log jam and previously the clay pits and it is probably about to change.
