There are also parasites in Lake Ming. Bird parasites. There are signs warning against swimming there. Each body of water has its good points, and not so good points. I know the Pacific Northwest has some of the most beautiful water in the world. Crystal clear, no odor, plenty of fish.........BUT OH SO COLD, Burrrrr. As boaters we have to use the water available to us. Just be careful with the little ones on the crew. Kids love water, but please be careful..........Ray
