When we launched our boat at Stone Quarry boat launch in Sturgeon Bay the local fire department and law enforcement personnel from Menominee, Wi were practicing water rescues and recoveries. They were sinking a boat on purpose and then diving down to it. We didn't really understand what sinking the boat was all about since they typically don't bring boats back up -- just bodies --but we didn't ask.
We had to take a picture of our pretty boat when we were beached again at Horseshoe Island. The water is such a pretty color and so clear you can see 10 or 12 ft down in most areas of the bay. They say the zebra mussels really cleared up the water. We talked to a guy from the DNR and he said the zebra mussels have just about died out but now the Quagga mussels are taking over --another exotic species. Its a never ending battle with exotic species on the Great Lakes.
We are gearing up for the onslaught of campers coming for the 4th of July holiday. The campground is almost totally booked so its guaranteed to be very, very busy.
