I'm still cruising through past posts, & I see a lot of people carry the large garbage bags for various uses.

The largest bag I've seen is 3ft.wX7ft.long, probably about 1 mil. thick. They are used for Christmas tree cleanup. You can often find them right after Christmas for a dollar.

I think of them as cheap tube tents with one end closed against the wind. I keep one in the truck and one in the bottom of my BOB. Cheap insurance. <img src="images/graemlins/smile.gif" alt="" />
