I'm in Hack's and Destry's debt for explaining a pigeon shoot in America. I knew they came out of a box (and maybe thrown by a man in Spain) but not that they had to fall within 35-40 yards. That changes the water on the beans right there. I wouldn't think of using a 20. My curiosity will be accommodated if I knew what happened to the score if a crippled bird flaps past the line.
