Regarding road flares. Olin corp, now known as Orionsignals makes a convenient 2 pack of 7 min flares for the purpose of fire starting. I know you used to be able to pick them up in Walmarts outdoor section for something like $5.00 for a package of two.

I am not seeing them on walmarts page, but then I didn't go through all 18 pages of "fire starters." although they did have this interesting device you will no doubt recognize.

The Flare type starters are available from Orionsignals:

Either way, they are handy and efficient fire starters. I have a few packages of them that are approaching 10 years old or so. I'll have to dig them out and see how well they have aged.

Ah, what I wouldn't give for a pre 1990 box of Diamond Strike anywhere matches. These days, they are strike NOWHERE!
