I must be turning into a total camping geek because I cannot stop reading all the info at zenstoves.net. I have one of those tiny canister stoves (MSR Pocket Rocket) that’s easy to use but a bit unwieldy with those heavy canisters, which are a pain to dispose of and always force you to haul more fuel than you need, especially on overnight outings. Zen Backpacking Stoves has tons of advice on building your own stoves and describes all the various fuel choices. Great stuff. If you’re a camping geek. (Link via HikerDude).
