[pct-l] disposing of fuel canisters?

[matthew lesniewicz]

I will be using canisters as well. But also going to to keep an alcohol stove in my bounce box as a back up. My concern is actually disposing of the canisters along the trail/towns. Is this something that will need to be mailed out back to home every time and dealt with later? I know the quick fix would be to throw them in the trash discretely but something doesn't seem right with that. For anyone carrying canisters how do you go about this?
