Kooty, you lucky dog, don’t ruin your moose-hunt by taking an inflatable air-mattress! I’ve spent a lot of nights in the BWCA when I worked for the Forest Service on various types of mattresses and I can tell you when it comes to thermarests it isn’t if it will let you down, but WHEN it will let you down. Ever try to play basketball in the winter out in the drive-way? Ball doesn’t bounce too good does it? Same with anything inflatable in the BWCA in October. Here’s what I suggest…get a 1/2″ closed-cell foam mattress. They will never fail you unless you melt it! I have a system for the BWCA in which I use 2 army duffles, nothing more. You roll up the foam mattress and place it into the duffle allowing it to un-roll itself and act as a protective liner for the inside of the duffle. Next, you place your sleeping bag inside of a garbage bag down into the bottom of the duffle. Your clothes and towel go on top of that in another garbage bag. Finally, on the very top you place your rain-suit. Close the flap and you are good to go! All the other loose ends, cook gear, and fishing stuff goes in the other duffle. Army duffles are perfect for laying crossways in the bottom of the canoe under the center thwarts. Place your tent in the crevice between the two duffles and your have a well balanced and low center of gravity load. Your guns and fishing poles fit nicely along the sides of the canoe between the canoe and the duffles. I have two rules in my canoe…if it don’t fit in the duffle it don’t go, and each man carries his own duffle. That helps cut down on un-needed crap to carry. Good Luck up there! I got some pictures of a nice bull on the lake I told you about, where I saw two good bulls a month ago! I’ll send them to you for inspiration!
Oh, did I answer your mattress question???
