Until recent years, law enforcement, fire departments, and medical responders all used public airwaves to broadcast calls to first responders. Anyone with a radio scanner could listen in. But that’s rapidly changing, and not everyone is happy about it.

Tour Minnesota's Fanciest Mini Golf Course - The Centennial Lakes Putting Course

While they won't call it a mini golf course, it kind of is. This 18-hole course boasts all real grass playing surfaces, natural obstacles like sand traps, boulders, and water, just like a real golf course.

The whole course looks and feels like a shrunken golf course, and it plays like one, too! The holes are long! The shortest hole is 57 feet, the longest is 125 feet, and the whole 18-hole course plays 1,662 feet.

This is no ordinary mini golf course!

Take a tour.
