I had to go dig this thread back up. There is an article on this thing in the current Field and Stream, page 24. It looks like a good peice of gear, especially if you ever break a leg or worse. It sounds like it would actually get more use from me just letting the wife know that even though it is dark, and way past when I said I'd be home, and I have no cell phone reception but I just got back to the truck and I'm just fine.
Life is hard. But it's a lot harder if you're stupid.
