A great ride, but one that almost resulted in disaster, due to two spoke failures. The first happened while Hilary, Karen, Eva and I were approx. 3 miles outside of town. I limped in, rear wheel wobbling badly, and was able to get it replaced. The latter happened on my front wheel, in the middle of a steep, >10% descent on Sweetwater Springs Road. This was truly scary, as I could have been easily resulted in being pitched head over heels as the front wheel rim, suddenly badly out of true, locked solidly against the brake pad. Somehow I managed to stop, but when I tried to walk the bike to the side of the road, the tire would not roll at all. The ride itself was beautiful, filled with interesting sights, vineyards and northern California redwoods. Had it not been for these technical failures, it would have been easily the most beautiful ride of the week.
