I had quite the opportunity back on January 26th. There was a big snowstorm blowing through for a few days over the Huachuca Mountains by Sierra Vista. I would say there was 18-24" up at 7000 ft. I took the sled out and put on 40 miles running up and down Carr Canyon Road to Ramsey Vista Campground. This is about 8 miles from the US/Mexico border. I would guess I'm likely the record holder for southern most US snowmobile ride!
