First time I drove my truck on the ice was on Michigans Houghton Lake. To say I was nervous is an understatement. Before I went on the ice I walked out about 100 yards with my auger to check ice thickness. I augered and augered and augered until I was down close to 18". When I finally broke through there was no water under the ice, only sand. Dulled a new set of blades.
