I've had a major outdoors adventure nearly every other weekend for several months now -- today, I ascended Sandia Peak with a running partner after we were told by several forest service people that the trail was impassable. We got off the trail and had to vertically ascend a skree field in 3 foot deep snow. It was great. Two weeks ago, I "bonked" (i.e. my muscles began not working, due to exhaustion, dehydration, and a lack of glucose and electrolytes) after running up a big hill. That was great too. At this rate, I know there will be a lot of fun in Tahoe.
