Chuck and Andy visit the Great Lakes, home to 1/5 of the world’s fresh water. The guys learn about the formation and history along with the preservation of the Great Lakes. They find out how big cities are learning to live in harmony with these precious resources. The Glaciers of the last ice age fascinate Dr. Greenie. He reckons if he can lasso a giant meteroite he can prevent a water shortage. GP gets wrangled into Dr. G's hairbrained scheme.
