Ski doo trails have been groomed but are rutted up or full of ice chunks. If you went later in the day once things had softened up a bit with waxless skiis this would work. Anywhere flat and open is great for skate skiing, and likely for regular skis as well due to a cm or so of granular snow on a very firm crust. Might I suggest the Migic Marsh where the TC Trail crosses. Also so far the ATV trail hasn’t been extensively groomed and I found it to be great gonig but that was on the other side of Mountview.
