Lost lake is like any other mountain riding. The bluebird days come with cold and wind and the snow sucks. The really really good riding isn't super frequent. You need to wait for spring time.
I rarely ride before december just because it's hard on equipment and because it's dark and cold. Come Jan-Feb we mostly ride petersville because it's closer and there is a bit of good riding to do that way, then March and April we turn south and ride the peninsula.
This year I'm just putting around with the kids on old sleds because I sold my mod sled and I don't think I can swing a new one this year. What I really want doesn't exist unless you are willing to part with a bunch of money. 170hp in a pro ride chassis.
