A Minnesota couple is approaching the end of a three-year, 11,700-mile kayak odyssey.

Dave and Amy Freeman, of Grand Marais (muh-RAY') set out from Seattle in April 2010. Their journey has taken them up the Pacific Coast, across the Arctic Ocean, down to the Great Lakes, out to the East Coast, and down to Florida. They plan to reach Key West around April 6.

The Duluth News Tribune reports ( http://bit.ly/YdegnM) the Freemans are using their journey to teach 100,000 students across the country about the outdoors through a website called the Wilderness Classroom. Both are committed to teaching through their travels. This summer, after the expedition, they plan to bring youths from Chicago to Minnesota's Boundary Waters Canoe Area Wilderness and do other programs in the Chicago area.
