Summer was short and hot this year...

And now it's over. The lake temperature is falling with each frosty morning and every degree Fahrenheit lost brings it a step closer to hard. To memorialize the surface of the lake's coming solidity, here is the 13th Annual Knottlane Ice-In Contest.

Pick ice-in, win money!

The rules again, are simple. The first person to pick Wisconsin's Lake Lucerne 2020 ice-in date here wins $50.00. The second person to select that date wins $25.00, the third wins $15.00, and the fourth wins $10.00. Any picks after fourth place will win our admiration and thanks for playing. One entry per person. About every 24 hours, we'll put pending entries into the selected dates area after they're purged of dups and bots. Until then, pending dates will be listed in the "Pending Dates" Column. The decision of the judges (The College of Loons, Lake Lucerne's oldest and most mysterious semi-secret society) is final. This offer is not valid in any state or country where it is not legal. No purchase necessary. Any malfunction (software, firmware, hardware, Loon(s)) voids all plays. Good Luck!
