I am hoping someone can help me estimate how long one of those little green propane canisters will run a 2-burner Coleman stove. I am guessing (?) they are a bit safer than a big tank to travel a couple thousand miles with. We will be cooking several easy/quick meals (oatmeal, a couple chili nights) for a group of 32 for a week.
Also, does anyone know a good place to stop for camping gear (e.g. the little bottles, topo maps) along I-15 (anywhere from Alberta to Death Valley NP) without venturing too far from the highway?
