 Yes, a stove, that's one thing that's always in my backpack, something, and I like the lighter weight ones like your isobutane stove, but there's your multi-fuel stoves as well that'll take like kerosene or your white gas. Those are really nice stoves as well. You bring up a good point here. There's different fuels. There's propane ones. There's isobutane. There is multi-fuel stoves. Some of them even burn diesel fuel. How do people make a decision as to what will be the best for their application?
