Anyone know the story or some information on that pretty red PistenBully wide track groomer that sits by U.S, 41 where trail-3 crosses about three miles south of Brockway Mountain Drive in the U.P.? The caution signs suggest that riders might encounter the groomer while traveling on the trail there. Thought it might be there for testing purposes or demonstration or something, but in many travels past this we have never seen it moving or anyone around it. Just wondering.
