In reply to Drew52:
Comes in US gallon cans - no need to provide containers.
Also found a Jetboil handy at & above 14K last time I was there.
From my three trips (all in June though) I would say don't over-provide (anything). I have given away 100s of dollars worth of food & fuel (my own & others) at 14K on all trips. Conversely it seems you can vary the diet quite a bit by barter up there.
