Also if you are planning on spike camping do you ship your fuel canisters out or buy when you get there. I am nervous about not being able to find some when I arrive.
Missoula a town geared toward outdoor recreation and they have a Cabela's , Sportsman's Warehouse, REI and more, you will be able to find Iso-butane canisters or other fuel at any of these places and even the Hardware stores.
There is a Missoula Map maker (Cairn Cartographics) that makes some amazing topo maps of local wilderness and other outdoor recreation areas. If you have an idea of the area you are thinking about a good map would be handy to have in the planning process and in the field. This trip should be a great adventure.
