Falling through ice and starting a fire
There is one recent thread that I especially liked.
They discussed a scenario of falling through the ice and needing to start a fire.
Lists and photos of waterproof fire-starting kits that are carried on the person because the sled/pulk/toboggan is still in the lake.
A poster from Norway (or Finland or Sweden) has ice picks that are carried around the neck to facilitate the process of getting out of the ice water.
Made me realize how much of an amateur I still am.
