Thanks for all these outstanding suggestions and tips. The airfare from NJ to Reno NV is much cheaper than LAX or Las Vegas so we would come in from the north. I'll check out the links you've all suggested. I get a feeling the higher I stay the better before attempting Trail Camp at 12,600 with a 25 lb pack on the first day. Like the gent from Atlanta, I had tried Whitney (back in 1989) and made it over Trail Crest but not much farther due to AMS symptoms. This time, and with experience behind me, I want to make it!
I did not know Tuolumne was so high..I thought most of Yosemite was around 4000. I'll put all the suggestions on the table and come up with a plan for a two week "acclimate-play-and pulp ourselves on Whitney", which I'll post back here probably next week. You are all so wonderful and helpful! I can't thank y'all enough ...this vacation is really going to be special even if we don't make the summit. And of course ther will be a trip report.
