Both of you have good suggestions, and we would be wise to follow them. Our deal is that we recently summitted Shasta, and our desired next stop is Whitney. We would arrive very early and have almost one full day to get acclimated. As a group, the extra day is problematic.
I noticed that usage in June 2012 was heavier than in June 2011. Weather perhaps? If it is increased interest, hopefully the usage will level off to last year's pace.
Anyway, you folks have given us the lay of the land, which is very helpful. Thanks.
