Right, those are for canoe trippers who like to cook with wood. There are many places where this is still acceptable. You can get a couple of cook pots and a coffee pot on one of those without uglying the landscape.

I have one of those charcoal chimney starters ($10 on sale) that would actually make a pretty sweet portable wood stove. Too heavy to backpack except for a base camp, but handy for canoe or car camping. A swatch of insulation under the base would protect a picnic table or forest floor. One of these days I'll get around to firing it up.
