The Definition of Trap
A game of competitive clay pigeon shooting on a formally designed layout. In plan view, one launching machine is located 16 yards in front of a straight line,
firing rising targets perpendicular to and away from that line. Five competitors shoot five individual targets at each of five stations along that line.
Although each target is presented at slightly randomized vectors, trap emphasizes generally a single type of shot, outgoing and rising,
and targets are broken at generally longer ranges than Skeet.
