Mt. Whitney-2009?

February is the month the Mt. Whitney lottery opens up. It brought up the question, "Shall we go again?". If we do make another attempt, will it be another easy 2 nights on the mountain or will it be the "do it in a day" madness that seems so infectious?
I enjoyed the backpacking, the night in the higher altitudes, the camaraderie with the other campers and the feeling of accomplishment after carrying the 40 lbs to Consultation Lake. The leisurely pace allowed us to take in the beauty of our surroundings.
If we try do the the same hike in a day, there is the added pressure of time, weather and stamina.
There is also no time to acclimate to the altitude, which was a big factor in reaching the summit last year.
We have a few weeks to decide.
