Seven old-time steamboats are chugging up the Mississippi this month, the largest flotilla to ply the Big Muddy in 150 years. The Grand Flotilla, June 25 to July 5, marks the birth of river tourism when, in 1854, trains from Chicago reached the riverbanks to deliver cruisers. From the Quad Cities to the Twin Cities, it’s a perfectly patriotic way to spend the day ($148) or an hour ($25). (866) 439-2004, grandexcursion.com
