Pipeline Trail to get out of the condensed pollution in our fine valley. Started at Burch Hollow and went up the hills to Elbow Fork and put a little add on to get to 4 miles out and back. Legs burning on this one. Havent done much hill work for awhile. Beautiful views of the mountains today with a lot of snowshoers and crosscountry people on the trail. I held myself in check today and only pushed three of them off the trail. I love watching them roll down the steep mountain kicking up a dusting of fine snow.
