I know there are some snowmobile clubs in the northern states using them as they are restricted as to the size of the machine they can use on their trails and it's a bit warmer grooming with one of those instead of a snowmobile. If I recall, there was one club running 5 of them pulling smaller drags. They had pictures over on Koz's site. Also a few pictures of them stuck and digging out in a foot of snow.
