One year, about 10 years ago, can't remember for sure, but my brother kept opening up a point by Mobridge with his little 12 ft Jon boat. That little spot right on the point he kept breaking it open until there were guys walking out and ice fishing pretty close to him. I know it was well into December, if not January. I think he may have went once or twice in January, I can't say for sure. I went out with him at least once in December but not sure if I went again in January. I know that year they didn't have the big ice tournament.
