This shoot was always considered a "money shoot" even before it moved to Linn Creek from Mexico. It grew along with the popularity of the sport in the late 80's, until a few years ago.
The money has gone out of it for a couple reasons. The perception is that short yardage "target management experts" occasionally skinned the purses. Couple that with the the "big-dogs" who knocked off the money the rest of the time. The average trapshooter lost hope that a fair game could be found there, so he has kept his money in his pocket. Not just in Missouri, but option entries are down everywhere, the money is mostly out of this game and not likely to return if things do not change.
The format change for the weekend did not seem to excite anyone this year. People who do not play the handicap money want to shoot all three disciplines every day, that is why pre-Grand remains popular.
Banks held for the "big dogs" in front of the clubhouse, the usual mud or lack of gravel, $29 targets, expensive motel rooms, and so on make it easy to find an excuse not to go there.
