I was told this story by a buddy.
He had a family trip to SD this year. There's a guy who's lived out there a long time, let's say he moved there from MN 30-40 years ago. He had a good career and bought a chunk of land, the thing is laid out just like one of those prime Game Production Areas, except it's private. I think it's a quarter or half section, can't remember. Foodplots, treerows, crp, the whole nine yards. The guy is older now so doesn't hunt much, but invites his friends to come out. My buddy and his son, along with his cousin(s) etc. were invited out. He was very appreciative of this and had no complaints, all had a good time. Then he tells me after all the stories about birds shot, seen, etc. that the guy bought a pile of pen raised birds and had them released before season. My reply, "??????????" My buddy thought he either felt pressure to produce, or maybe it was ego where he wanted everyone to think he had a great property where they killed a bunch of birds. I was really confused. When you have a sweet property gobsmack in the middle of prime SD pheasant territory the last thing I would ever do is release a pile of distended nostril toe-clipped roosters. This was not any kind of resort or "guide" property. On the contrary very few people hunt it a year. Just an example of how it may be difficult to figure an exact number of released birds are blasted in the Mount Rushmore State every fall.
