Have you been out to Rattlesnake out west? I've had a couple good trips out there with some snow (nothing deep) At least that's what it was called when I was out there wheeling which has been probably 8 years ago! I am occasionally on the rocky mountain extreme 4x4 website which has more local guys out there!
Another option is going up to the Bountiful B. There are some fun trails in the snow up there. Watch out for the mud holes though. I hydro locked my old 4runner in one that went over the hood!
