The boating parties pedaling in such stately fashion across the Tidal Basin are coming as close as any of us are going to get to walking on water. Save spending the day in the bathtub, they also are the cheapest of Washington's watery pleasures.

There is the pedal boat for the penny-pincher, and, priced on up, canoes, rowboats and sailboats. The lazy river will lure us all.
