Thanks everyone.

Although I am interested in this topic for multiple trip locations, I was thinking particularly about a Grand Canyon trip where I would arrange a re-supply via mule for a large group (11 people) on a rim-to-rim trip. Doing the re-supply would help keep our weight down and also perhaps permit using some "heavy" items rather than all freeze-dry or just add water meals.

This will be in early June with possibilities of a variety of temps. When I was there in late May '08, we had snow flurries on the rim and high 80s in the bottom. It could just as well be 60s low on the rim and low hundreds highs at the bottom.

The thing is, the mule duffel would have to be packed before we headed over the edge, so it would sit on the rim for a couple of nights before it came down.

Beyond the egg thing, I'd welcome menu suggestions for this trip.
