I've used several of the above for fires and all work. The Bic won't light below certain temps though. Anyone know what temp the liquid turns to burnable gas? Keep some matches or other ignition sources close to you. Some in or on each vehicle may save your bacon some day. A time or two they have been handy to me, even though not strictly an emergency. That Boy Scout manual could be a lifesaver. I'm going to give each of my kids' families one for Christmas. I like to give space blankets and such for gifts. This great grandpa is a softie and has a concern for all things family. Be Well, RZ.
