Have not road that trail but Moose country club does groom it and I did ride some of there trails and they seem to do a really good job. Iron River club has been getting out quite a bit lately and there trails have been good from all the people I’ve talked with.
Have not been on that trail this year but will be later this week.....
Chippewa Snow Kats take care of Tr 18 from around Amasa for about 20 miles in and Moose Country from the turnaround into Republic
Both clubs are grooming
Hope that helps
