After hiking just over 300 miles, my right knee hurt enough to force me off the trail. I'll rest my knee for a couple of days and try again. This knee has given me problems in the past. I had hoped it had healed. It hasn't. It will make hiking the entire trail in one year impossible. Many parts of the PCT are equal in beautiful to anywhere in the world. I'll be sure to hike them. My left knee which was replaced last October has not totally healed, but is functioning OK.
