Alan - I would love to hear more details of your 2006 trip sometime. I have dreamed about doing the JMT in under ten days (so anything 9 days, 23 hours and 59 minutes or less), unsupported, without resupply. Pretty much everyone thinks I'm F ing nuts, but I think you and your son pretty much did what I want to, but even faster.
My rough plan is to have a little sherpa type help getting to the Whitney summit with my gear and then leaving from there at midnight. Any gear, food, etc I decide not to take at the last minute, they will carry out. I am not counting the 11 miles to the summit as part of my trip. I expect to leave well fed and well rested.
I've heard there is someplace in our near Yosemite that I can get a burger very near the trail. I wouldn't consider a burger or four along the trail a resupply. Then again, it's my dream so I'll make up the rules.

My wife is pushing for me to have it done by July 31st so I'm legally still on active duty. I'll have to monitor all the reports to see if that's doable. Otherwise I'll go for mid/late Aug.
All this assumes my practice hike from OV and out Bishop Pass goes ok.
Any wisdom you can pass along? Thanks..............................................DUG
