(Cass Co.) The Cass County Conservation Board is inviting residents to predict when the first trumpeter swans will arrive at Schildberg Quarry this winter.
Trumpeter swans have visited the quarry for at least 27 of the past 28 winters. Residents can submit their predictions by calling the Conservation Board at 712-769-2372 by November 11. If no one answers, callers can leave a message with their prediction and return phone number.
Only one prediction per family is allowed, and each date can be chosen by only one participant. For example, if a caller predicts November 25th, no one else will be allowed to predict that arrival date.
The contest will close early if more than six trumpeter swans arrive at Lake 4 before November 11.
The winner will receive a trumpeter swan prize from the Cass County Conservation Board. The contest is open to Cass County residents only.
