If the weather holds up and I can get a permit, I'll have a trip report for you next Sunday when I come back.
That's not a good story to hear Terry, but I'm glad you and your son made it back in one piece. Your son has the same problems as I do: easily susceptible to AMS, and too much adrenaline. I do fine as long as I keep a "conversation pace". I've gotten excited before and blew up a mountain and immediately paid the price with nauseating headaches.
Sleep at the Horseshoe Meadows campground as Steve said. That's 10,000 ft to help you acclimate (not to mention the drive up has great views). You guys sound tough, a dayhike shouldn't be a problem. LOL, if I can do it, anyone can.
