I live just outside of Chicago. With the weather we've recently had, sub freezing, I've noticed that butane lighters left outside will not work. Like canister stoves, when the temp drops into the extreme ranges, pressurized gas devices will not work!

Make sure your PSK and BOB contain spark lighting systems, ie cotton balls and pj or 0000 steel wool.

We have discussed this before on this forum. My cold weather kit contains a zippo, lighter fluid, flints, and the old style hand warmers which run on lighter fluid.

KISS, the 7 P's, and multiple redundancy prove Darwin right.
