Mike, very nice work and great visual aids. I'm sure it took a lot of time and I for one appreciate your effort. Just wondering, what were the distance(s) of the circle testing and of the birds in flight? I like how you showed that clumping on the last flying bird. (Private joke - like I blurred that reflection in the B-W trophy pic, MODERN TECHNOLOGY!) Frank
