On the road

Day one

Minneapolis to Duluth, 150 miles. Catch an early flight to Minneapolis to give you time in the afternoon to explore Duluth's exciting Lake Superior waterfront. Duluth is the leading Great Lakes port-about 1,000 lake and ocean vessels call here annually-and one of the busiest in the country.

Make your first stop the Lake Superior Maritime Visitor Center, a free U.S. Army Corps of Engineers facility at Canal Park in downtown Duluth. It provides an excellent introduction to shipping lore. You might catch a freighter sailing into port; the museum posts an updated schedule of expected arrivals and departures. Most ships enter empty and depart full.

I was particularly interested in a large, illuminated map that helped me identify the harbor's major terminals. The Midwest Energy Terminal loads coal brought by train from Montana onto carriers supplying electricity-generating plants in the lower Great Lakes. Iron and coal are the two most important cargoes. There are also six grain elevators capable of holding 55 million bushels.

Elsewhere in Canal Park, step aboard the William A. Irvin (adults, $6.75), a former iron ore and coal carrier turned museum ship, for a 60-minute escorted tour. Save an hour for another Canal Park attraction, the Great Lakes Aquarium & Freshwater Discovery Center ($8.95). Here I learned that Superior is about 350 miles long, 160 miles wide, and holds 3 quadrillion gallons of water. I suppose the huge, whiskered lake sturgeon-almost as big as sharks-feel a bit cramped, even in the aquarium's giant, 103,000-gallon tank.

And while at Canal Park, enjoy dinner at one of its busy restaurants. Little Angie's Cantina & Grill offers a nice roasted-chicken enchilada plate ($8.99), served outside on the lake-view deck. Or walk uphill to the Radisson Hotel, which features a revolving rooftop restaurant, called Top of the Harbor, with sweeping harbor views. With the early-bird special (4:30 p.m. to 6 p.m., Sunday through Thursday), every entree is $7.95.
