very handy in the snow
my friend had these last year when we went camping on mt rainier and they worked so well i immediately bought a bunch for my tent. they wouldn't work so well in powdery snow, but in packable snow they are perfect. they work best if you first attach them to your tent with small caribeeners and stretch them out to see about where you want them. then dig a hole about 1-1 1/2 feet deep. then make a large grapefruit size snowball to put in them to start. pull them taught, and pack more snow around and over them, stomping it down tight. i was in a snow storm the first time i used them for myself and the tent never budged.
