Hmmm, interesting idea if I get the gist of what you're saying about the walk-in. I'm beginning to wonder what kind of a "Whitney" experience this is really going to be, seeing as I'm really getting none of the same trail we did last year- except for the last leg. I've also thought about getting walk-ins for 3 days later, do the Crabtree Meadows thing, and return for a same MMWT summit through the Portal. That's a lot of hiking! I'm also wondering if 4 days is enough to really enjoy a trip to Whitney via Cottonwood Pass. That's an average of 15 miles a day, in terrain I'm not sure of as far as how difficult it is. I'd love to hear some thoughts on that.
