Ok now for my .02
get rid of the teva's unless they are flip flops and get some crocks. My husband and I use those shoes all the time on trips like that. They are so light wieght it's not even funny.
And as far as the stove thing goes deffinatly find out if you can share with someone. If not you need to bring one. My dh and can survive on just using a large stainless type mug or enamelware . That you can heat on a stove. We use them for cereal, soup and tea/coffee.
And please tell me you are going to bring a parka for rain or something? Never risk something like that! Besides you don't want the other people in your group to have to worry about you when it comes to that.
But see if you can share a stove with someone and offer to carry some of thier food maybe.
My dh and are want to go with you! We will share our stove!
