From Tampa with a group of 4. Stayed in Lone Pine day 1. Hit the trailhead the next day and pitched tents at Trail Camp. All of us pre-medicated with Diamox. Awoke at 2am and hit the switch backs at 3am. I think the switchbacks are easier in the dark(keeps you from looking up and seeing how much farther you need to go). Reached the summit July 19th 3 hrs after leaving trail Camp. I usually never have a problem with altitude or with accents, my biggest challenge is the descent, very tough on my 58 year abused old knees. It took me longer to descend to trail camp the the accent. The hardest part for me was the descent from Trail Camp to Lone Pine Lake. Stayed 1 night at Lone Pine Lake and had an easy decent to the trailhead in 1.5 hours. My younger companions found the decent easy. One of the party struggled on the accent and was hours behind us, but did summit. One of most beautiful places I've visited. I appreciate all the posts that help our crew having a successful summit.
