We rode GMR/GRR Sunday to about mile 18 or 19 from the gate and it was clear and very quiet (one skateboarder, 4 or 5 motorcycles, lots of hunters and a game warden keeping an eye on them). Once we got past the GRR/GMR split the road was wet in places and there was a small amount of ice here and there, but nothing that posed much of a safety issue. It was crazy cold on the descent - my Garmin read 36 degrees when we were near the water tower (around mile 13). Bring your booties and balaclava.
