I think you have it backwards, if it wasn't for the large number of riders paying $20 each there would be no groomed trail at all. Friday things were good, Saturday the way back was rough but still bearable for most.
Rode both Salmon and Groundhog this past weekend and snow was unreal. Didnt see any slides or movement at all and even cutting into sidehills the snow seemed setup. Trails sure need a groom though but have riden worse. First time in Blue River ever and will be back forsure.
