You want to talk about stupid...
At one of the airports I fly out of...the idiots in the county decided to build a nature preserve swamp out right beside it. OK, the bird problem was bad after that.
Then the same geniuses decided to build a feeding ground. No, not where the birds would fly farther away from the airport. No no, they build it diagonally across the airport a couple of miles away.
So, the damn birds fly ACROSS the airport in massive flocks about twice a day to get to their feeding grounds in a straight line.
