Dj2 I checked out your photos and they look very interesting! Yep with that simple a bag I can see how you can do it for a pound. You'd have to be wondrously organized.
I'm still considering any way I can to lose a pound or two for the big 4....and the sleeping pad is the first thing I'm considering, going to a Neolite would save over a pound!
