Hey Gary,
you've probably seen my plans. I'm going to try for the Whitney permits, but if I don't get them, I am planning on bringing my son and a couple of friends up to Meysan Lake and do what you suggested.

I'm planning on going up Memorial weekend and doing a day hike as far up Meysan trail as I can go without needing any special snow equipment (cramps, shoes, axes etc....).

I'll let you know how my scouting trip goes.
