My wife and I just got back from an Alaska cruise we took for our 25th wedding anniversary. One of the things I did while on the cruise was this thing called the White Pass and Yukon Rail/Bike Adventure. The trip was pretty cool, if not what I would consider a real ride. We took a narrow-gauge railroad from Skagway to a place called Fraiser in British Columbia. There we got off and picked up our bikes, which we rode back down to Skagway. The ride down consisted mainly of riding the brakes to stay with the group. There was one very short uphill stretch, but the rest of the 15 miles or so was either downhill or flat. I even took to pedaling backwards just to keep some circulation in my legs and warm them up . I'm sure the other riders thought that was pretty strange. The guide said that they replaced the disks on the rear brakes every week and the front every other week.
The ride itself was beautiful through. It rained on us a bit and it was cold, but it was very much worth the time it took. Here are a few pictures:
