I'm back from two weeks of rafting down the Colorado through the Grand Canyon. At one point (the narrowest point of course), I actually swam across the Colorado. Never thought I would do that! Other than seven dislocations of my meniscus, and therefore not being able to climb in all the slot canyons, it was a great trip. I've had my knee checked out and have been given the go-ahead to continue cycling. The first three days on the bike were in the 60s rpm and 35 minutes, but I expect to go longer and more quickly today. I'm eager to get back into my regular cycling routine. Amazingly enough, other than moving more slowly than some, my PD did not get in the way of participation in the trip. One evening I gave a presentation on PD. Six people came to the start and within minutes nearly all of the 28 were there, staying well into the dark for q and a. Pedaling trumps PD yet again!
