I've never hit one, don't plan in it , but it can happen to anyone, including me. My brother hit one January 7th this year up by the damn in Red Wing. He was out fishing with our dad, stayed a little past dark. Luckily they were barely on pain and going down river. The marker actually went under the boat, only damage was to the bow cap. MY FAMILY KNOWS BETTER. We grew up on the river It was extremely cold out that day so my dad was facing backwards in the middle seat of a tiller style boat. That marker lined up perfectly behind my dad the whole time. Luckily no one was hurt, just real scared.
Sorry about your 153.
