If you hear some loud booms on occasion over the next few days, don't become alarmed, it's not foul play, it's just the city of Sioux Falls attempting to scare waterfowl that has moved into the area.
If you have ever thought that Canada geese crapping all over the bike trails and chasing people around are annoying, they are creating an even bigger problem right now at the Sioux Falls Regional Airport.
The loud booms residents and travelers are hearing on the north side of Sioux Falls has a logical explanation. So it's not a UFO breaking the sound barrier, then?
