It is amazing how the routes change over the years. I rode 2 up on a KLR with my wife up Imogene when I was 52. A few years ago I did it solo and wondered how I'd done it with my wife on back. Traction and scree makes a big difference year to year. Black Bear was no problem on a KLR, but on a 990 Adv with rain, it was. You never know until you get there.
