Check with the county that you are in and they will let you know what you have to do. In Lac St Anne it has to have a grade (2% I believe) then gravel and then polly on top of that. Also has to be on screw piles. Different countys, different soils = different rules.
I sharpen mine. Put it in the vise and use the angle grinder, then check it for balance. Once maybe twice a year. Have a friend that was sharpening his with the bench grinder last week and it slipped and he cut an inch off his finger.
Had a great day in Chappell yesterday. 8 inches in the parking lot and 2 to 2. 5 feet up top. Some wind blown at the back but that just meant some deeper pocket of snow in other spots. Blue bird day so snow was getting a little sticky on south facing slopes. Trail in was great, thanks...
Accident happened just after 4:00. Looked like it was heading north and slid across the highway and when it hit the snow bank over it went.
Road Clemina both Saturday and Sunday and played in untouched deep powder both days. Ride up and down was cool, but with an extra layer on it was fine...
