I accompanied my wife on a trip to a conference in Vail. All went well on our stop off in Steamboat at my sister's house. Nice trails, decent bikes. In Vail. however, I decided to ride the gondola up and give mountain biking a try. The first two runs were fine - I stayed on easy to low intermediate trails and kept well in control. On the final run I hit a deep rut or something while braking and went over the falls. I ended up with two breaks in my left wrist which will keep me out of action for a couple of months. I guess it is some compensation that they are hot months lousy for biking in DC. The worst part of the incident was getting down with a next to useless left hand.
