Dave went with some friends on a 47 mile backpacking trip the end of September.  I was a little concerned that he was going to have issues with his ankle since he hadn't really done anything that long on it but after a 10 mile warm up hike a few days before the trip he decided he was going to join and test his endurance.  He said it went well and although maybe being a bit sore, survived his trip and made it with flying colors.  They hiked the 47 mile loop in the Olympic National Forest.
