Hiking Mt. Whitney

As Linda mentioned..I will be backpacking to the top of Mt. Whitney, located in Lone Pine, CA on June 6-8, 2008; It is the highest peak in the lower 48 states...topping out at 14,497. I will be tackling this adventure with a friend of mine-Melissa. She and I will be going on a guided tour with Sierra Mountaineering International-I believe including the guides there will be 8 of us. I have day hiked around AZ and NM--but never anything quite like this...we'll be carrying 20-40lbs on our back, we will be using crampons and ice axe (for the snowy conditions)..we will be wearing harnesses, ropes, etc as we make our final ascent to the top via the Mountaineers Route. Their are many ways to get to the top--this just happens to be one of the more "difficult" routes...We've been training for the last couple of months now--and feel very much prepared for what lies ahead..Day one we hike to UpperBoy scout lake (11,000)-and put up camp...Day 2 we "chute" the summit and then back down to camp for the night...Day 3-we pack up camp and head back to Whitney portal (8,000) in time for a nice lunch or dinner I suspect...it will be amazing--and my prayer is a safe and exciting trip-to the top...and then of course safe travels back "home"...Your thoughts and prayers would be much appreciated!!!!
