I just gave a demonstration of dutch oven cooking for my ranch's adopted cubscout pack. The contents of my PSK led into a brief discussion of several topics that narrowed to signalling. I tooted my whistle, flashed my mirror and then demonstrated my bullroarer. I had the scouts enthralled, nudging each other,whispering,giggling and pointing. I ended with the warning that you had to have somebody looking or listening for the signals. More laughter,pointing and whispering. I finally looked around. The local vultures were circling in slow,lazy circles just above us and landing. 2 coyotes sat on the knoll behind me, ears cocked. 5 deer were frozen still behind the horse pens. I'd like to think it was the smell of cobbler and not my communication skills.
