Most epic ride: White Mountain
Labor day weekend 1982, two friends and I rode our new mountain bikes to the top of White Mountain 14,250 feet. I say "rode", but we had to push and carry a bit at the top. The last few switchbacks still had several inches of snow. Riding above 12,000 feet was unpleasant, it was like being really shaky hungry all the time.
I also did "The Death Ride" a couple of times. 1st time: Ebbets, Dagget, & Monitor passes (back when they did the original route). 2nd time Ebbets, Carson, & Luther passes.
