The good ones are fun, and the shooting is quite challenging; I don't think the online videos do them justice.
Ideally, the launch tower is hidden by trees, and the birds come blasting out at unknown intervals flying high and fast. The gap between the trees and the shooting positions should only be about 30 - 35 yards or so. Somewhere around 30% of the birds succeed in flying through the line, depending on the group doing the shooting. If you're thinking about the upcoming shoot at Hidden Lakes, I can recommend them without reservation.
