In my backyard, there is a public forest where I use to go for MTB in summertime. The singletrack loop is about 5km. This winter, instead of just snowshoeing them as usual, we decided to groom the entire loop. We just pull a homemade grooming devices with harness (remember Muscle Over Motor?) the winter ride is smoother but a bit more "technical" because every time you fall, it's deep snow both side of the trail!
