i don't intend to start any riots here. However, just as with everything else when it come to hiking skill is what makes us safe, not equipment. A small fire built by someone who knows what he is doing can be a safe alternative to a wood stove. I am not advising people turn the wilderness i love into one giant fire pit. There are places that make sense for fires and places that don't, and stupid people can ruin either.
When i hike in places where others have clearly had fires, mostly in heavily visited sites where there is one area that people have used over and over for a fire, i don't hesitate to burn a small one myself.
And here is how this actually pertains to this thread...
When visiting a place i know it is responsible to have a fire i leave my stove and pot at home. Instead i carry my water in a 16oz Caribou coffee can. It is and aluminum can like a Pepsi can but it has a screw top lid. I carry one lid for water transport and another for burning. The burning lid had 4 1/8" hole in the top (used ti stake to make) and has the plastic insert burnt out. I use 1 stake pushed through 2 of the holes as a means of retrieval. I toss it into the heart of the fire, lid up, and once it starts to steam i use a stick to pull it out by the stake.
I love this combo as i already will have the fire (0 grams) i already have to carry water (0 grams) and i already have a tent stake (0 grams)The only limitations to this system are the need for fire and the small capacity of a 16oz water bottle. I plan to try a monster 24ozer this season. I just don't need that much water boiled and am concerned about burning it with less water as it may melt the top of the bottle (that would suck)
