its always a challenge in the winter, iv only done it a few times (cn t.o <> van) in the dead of winter, probably the coldest -30C for 4 day IM, nearly lost me feet.. some people do it in the winter round -50C.
if your geared to fuck, and your cotton clothing doesnt get wet your fine. i like rendering a bunch of animal fat anything i can dumpster or find roadkill find and go with a few jars of it, a tablespoon is instantaneous warmth.
im always happy about wintercoming a bit more so then summer,
gives a good reset, kills all the narly bacteria that festered all summer everywhere, no fuckin mosquitoes, no more staph laying around moist squats..
summers got its viable parts, for people who dont like the cold and like to grow food i suppose.the main aspect i like bout summer is bein able to swim in freshwater mountain rivers and makin homebrew
