This was Lake Superior this morning. We went for a walk and ended up down by the lake and could hear a rumbling. We didn't think it was the waves so I walked down to the beach to check it out and Bill stayed on the bike path so his feet wouldn't get dirty and wet. A couple minutes later I see him a ways down the beach taking off his jacket, shirt, and shorts and then diving headfirst into the waves. It was a muggy 73 degrees outside this morning at eight and he said the water didn't feel too cold.
