I ride alone 90% of the time. The only time I ride with friends really is when I take trips out West. I'll be hitting Utah and Mammoth in Feb and March, but otherwise I'll be going solo at the dinky resorts around here the rest of the winter.
The best part about going alone is I don't have to wait for my friends' dumbasses to wake up and end up getting to the mountain at like noon. I like to be there for first chair unless the snow really sucks balls
