Well done Jack, I like the outdoors.
I'd like to go to the Ardennes this winter with a survival vest, and some sleeping gear - no tent, just a shelter like in your pic.
Offcourse it will get cold and maybe snow I'd like to stay 2 nights and 1 day or so just to see how to cope with it.
Thing offcourse is to get 2 other guys to come along, not so many fools around.
