Don't try any of this at home. That may sound like a lot of stuff, but it's called a survival kit for a reason. I also carry a GPS, cellphone, water purification kit, and paper towels. I find that these have MANY uses and weigh next to nothing. Also extra bootlaces.
Some people carry safety pins also, but then some people are just strange.
The pictures here are taken with a Kodak DC240 digital camera, with a 32M memory card. I use rechargable batteries and carry alkalines as backup. Clicking on some links will open new windows. No gnomes were harmed in the making of this website.
