I always carry what I call my 'bushpack', whether I'm on a skidoo, quad or in my boat. It's got all sorts of things to get me through a tough spot in the bush and I modify it somewhat according to the seasons.
Always in it though are:-mini maglite with extra batteries
-first aid kit
-knife
-sharpener
-roll of tape
-roll of snare wire
-compact fishing kit
-compass
-8'x10' plastic tarp
-hatchet
-canteen cup & small cookset
-instant oatmeal, dried soup, beef oxo, instant coffee, tea bags, sugar etc. Basically a couple days worth.
-matches, spare bic, emergency tinder/firestarter
-50' small diameter rope
There's other odds & ends in it but these are the main items.
I use it all the time but I've only truly needed it once, while freighting in the northern part of this province one winter, in January.
I was hauling a load of diesel on a sled pulled by a snocat when it broke down.
This happened late in the afternoon but it was dark already. I ended up staying there for 14 hours till daylight, when I started walking back the way I'd come to get back to the camp.
After walking half a day I made it back okay, but am very glad I had my pack with me, as well as a full sized axe.
It sure made a big difference!
