Lawnerd,
I am going to be on the trail Oct 1st with 10 of my friends as well. Are you doing a day hike or camping? I attempted a day hike 9 years ago with 3 other people and 3/4 of us didn't make it due to AMS. We went in late Sept and had beautiful weather. I am hoping for the same luck in weather. I figured we would have better luck this time if we camped on the trail. Maybe our paths will cross.
