Don't worry about braking on the way down Mt. Washington. Bike brakes cool much better than car brakes and you have compression to use, too. I've not been on the road up there. We took the Cog Railway in a blizzard. Interesting place. I still have the coffee mug that has a picture of the cat they used to have there that got caught out in the cold. I'd love to ride up there once. It's just a little out of the way from Seattle.
