Well if your being a "critical realist", then you must have a valid reason you say this?
First hand experience/anecdotal?
You could pull in far enough with a 4 x 4 on BH road that it wouldn't be visible directly from the road, unless the snowfall was too much.

Q-Dave leaves his CAT road grader parked on different KM markers turn-offs and has NEVER had anyone vandalize it. He'll hitch a ride back to his truck which he leaves the same way and no-body's bothered it?

I'd worry less about a vehicle being stolen/vandalized up there than I would anywhere a 50 mile radius of Detroit.

Dawson Campground is open all winter, so IF Jaximus was concerned about leaving rig, he could go that route.
As far as I know the vehicles parked at BH is paddling season have been safe. That road is good enough IF someone wanted to come in and clean them out they could easily.

Anyway I was just giving Jaximus some ideas since he said he wanted to go to Q.

Your critical realist opinion is just as valid as my more optimistic one so it's all good.
