I used to use "Heet" in the yellow bottle. My method of storage was a recycled/reclaimed plastic shampoo type bottle with the snap shut dispenser top. I secured this container in a sealed ziploc in a seperate zippered pouch added to the outside of my pack. Overkill, maybe so, but denatured alcohol is toxic. Read the bottle. The ingredients that are added to it are meant to keep those so inclined from drinking the stuff.
I have since moved on to Everclear. It rides in an upper side pocket of my pack without the benefit of the sealed ziploc. The container is a newly purchased "holy water bottle". It has the flip up style dispenser top. These bottles happen to come in 4 ounce sizes for less than $2.00 apiece at the local religious supply. They are flat sided like similar Nalgene style bottles. I pack two side by side in the one upper pocket.
Everclear is a great fuel. Its added benefits are secondary uses as emergency anticeptic and mixed with your beverage of choice in the proper proprtions a satisfying nightcap before turning in for the night.
I shy away from throwing it my pack because I use a plastic pack liner. If the worst should happen my sleeping bag would be swimming in the stuff as it's the first thing into my pack after the rolled pad.
Party On ! 2010
