The only experience similar to this type of hunting I have had is a deer drive during flintlock muzzleloader season. I can see your point Tim as there is a lot of anticipation there waiting for the drive to begin but you only have a chance at one deer, here there are multiple shots taken at all sorts of birds coming in at all differing angles at differing speeds. That would be a lot of fun.

What is the rules regarding a low flying bird? Let it go and pick it up on the next drive? Does the shooting line keep moving to a different position after the drive or are you stationary?
