Ah... minimalist camping... you don't have kids, do you? I love camping, but with the (young) kids, its the pop up trailer with all its lovely comforts! History has always been an interest of mine also.
In all honesty, I think most of us have a LOT of hobbies (I did not mention collecting swords, collecting miniature castles, pinball machine and casino game collecting, and writing). Those are 'back burner' hobbies!
