Recycle those canisters, please! If you (1) make sure the canister is empty (let it sit outside with the stove on it and the valve turned on full for 10-15 min.), then (2) punch a couple of holes and (3) let it sit outside overnight, you can recycle those empties! Mine go in my curbside recycling. Just be sure to follow the directions above so you don't start a fire (or worse) in the recycling facility!

My recent trip to California, which was supposed to include car camping on the way down and back, ended up in motel rooms both ways due to rain, cold, and wind. So my hope of using up several partial cans was a bust. I'll try again later this summer.

Also, since my backpacks (woefully shortened due to aging) will be mostly 1-2 nights, that's another opportunity to use up the partial canisters.
