I have been rethinking what goes in the pockets on the outside of my pack, and I realized I have been keeping my isobutane canister outside my pack due to something I learned in Boy Scouts many decades ago. Now I am not so sure about the wisdom.
The idea is that you should keep your fuel separate from your food in case there is a fuel leak. Granted, we were using white gas when I was told this, which probably has a higher likelihood of spilling (not screwing the cap back on sufficiently).
So right now my stove goes in my food bag, but my fuel canister is kept outside my pack. It seems like it would be easier for me to just store the fuel in my food bag.
What does everyone think? Where do you pack your canister?
