Take off your sandals, and soak your toes in that crisp clear water, but only a little past your ankles or the moment will have spoiled by the crackle of the beach nazis on atvs, "No SWIMMING! GET OUT OF THE WATER".
That's a shame. I recall last summer seeing some dedicated and well-wetsuited people swimming much closer to town, along the concrete shoreline to the north of Ohio Street Beach.
Swimming in the Great Lakes is not dangerous at all. They account for 14 drowning deaths per year out of 4500 across the country. That's a quarter of the annual U.S. drownings in the Atlantic despite having more U.S. coastline.
