No never been there, actually haven't been to the UP in at least a couple decades.
It was actually at Burt Lake many years ago when a sudden bad thunderstorm developed in the middle of the night. That'll get your adrenaline going, tall trees towering over you while you're in a flimsy tent.
Next time you're there check out the Nun Museum. It starts off with normal dolls but once you turn a corner you're almost startled to see these huge nuns towering over you. I'm sure it brings back some bad memories for some from Catholic schools.
