Yeah, Denny, I have a hat with a propeller on it too, but I got the optional generator with it and can now charge by headlamp batteries as I walk around on windy days.
And talking about strap on stuff, I have a strap on Fox Quiver with an Asbell arrow holder that I made years ago, and will hold seven arrows. However, last month, when I walked into the kitchen tent at elk camp, the girls were talking about strap on something or other, but they shut up when I came through the flap. Don't think they were talking about my quiver.
