Thanks Smithy. I didn't think about the lifetime of the tinder. I assumed that it being in a foil package it would be fine for a while. I have some "Tinder Quik" coming too: http://www.amazon.com/gp/product/B00029EWYY/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1 These are essentially cotton impregnated with something. I will try out the Weber stuff too. I am essentially putting together a GHB each for myself and my daughter and her husband. Simple and light, water, freeze dried food, some kind of light shelter (I have an Ecotat that I like, and I am thinking of getting two more for the kids) and a Cold Steel Survival Edge with a firemaking kit and compass in the hollow handle. The knife comes with a decent firesteel, and I would put some kind of tinder and waterproof matches in the firemaking kit. I doubt they would need to make a fire just to walk home if their car breaks down or something, but it doesn't hurt to have it handy. These bags would go in each car, along with a separate container with walking shoes, appropriate clothing for the season and a couple of other things for emergencies.
