Very cool Joe.
I'm working on a all natural winter shelter for the contest that's going
on in the W&SS forum over on BF.
Maybe you could build a snow shelter and enter that one as well. Would be
really cool to see what you come up with.
Mine isn't going to be a snow shelter as we don't usually get a lot of snow
in our area, but I'm taking a page from your book and am building a debris
shelter.

Cheers
