Went down 6 or 7 years ago on a lake just southwest of sisseton with my son. Despite only being yards from where we drove on, it was one of the most terrifying experiences of my life. It was late in the year and I had driven over that spot only a week before. Luckily we went down right on top of a submerged road. The ice was much thicker than the water underneath of us, so the water only came up to the floor of the truck. Two of my in-laws came out and sledge hammered a path back to shore and a tow truck reeled me in with little to no damage. To my boy's credit, he still wanted to go fishing! We walked out and caught a nice batch of perch.... I was really lucky that day. I put my boy's life in danger but by good fortune, the man upstairs, or whatever, we came out unscathed. It took a few years before I could bring myself to drive on the ice again..always only on a main path, unbuckled, with the window down, and with extreme caution. I never again want to hear that awful sound of ice breaking or have that "sinking feeling", literally. No ice is completely "safe"...ever
