Whenever we look at someone's kit I think back to the required food and gear Klondikers had to haul up the Chilcoot pass. I see that famous black and white photo and imagine some ultralight advocate arguing with the NWMP over his titanium cup's superiority to a dutch oven.You've acquired the one most essential bit of kit, a mindset of being prepared. I'd gladly grab your BOB as it now stands and run out the door.X and Y might prove deficient, but Z is enough to compensate and pull you through. Besides all the upgrades mentioned by people that will cost a MILLBANK Bag full of Loonies, I'd suggest buying the smaller and weatherproofed GEM version of Lofty's book. You will free up enough space to add more inspirational reading material ; WHEN BEARS ATTACK! THE MAD TRAPPER OF RAT RIVER a Farley Mowat Anthology or the greatest hits of Anne Murray and Celine Dion. With a small CD player those alone will eliminate any bear encounters.( Envision a black bear running down the trail, knocking over Lesley Nielson who sits up, hears SNOWBIRD and quickly passes bear.)
