I got this from Clarke Green’s website. In this article he talks about Disposable Propane Cylinders.
Again, as always, Clarke hits the nail on the head. Also, while I knew about the Solo Stove, I really liked his article about it. Clarke also blogs/talks about many other Scout related subjects.
If you do not know anything about Clarke Green’s website or Podcast (also on iTunes) and your in Scouting (no matter what part of the Global) it’s a good read and listen.
