What makes Miami a great city? It's the water, stupid. So when you're thinking about mounting your two-wheeler, and you don't feel like driving to the Keys, try the causeways north of downtown on a Sunday morning. Do it early when there's no traffic. Begin in Miami Shores at NE 96th Street and Tenth Avenue, and then meander south to 79th Street. Turn left and cross one bridge, then another. Smell the salt air. Revel in the views of downtown to your right. Look out upon Biscayne Bay. Then you reach Normandy Isle and Miami Beach. Next head north through the Beach's forgotten neighborhoods -- Byron Avenue is a pleasant route -- before reaching 123rd Street and heading west. Ahhh. Again the view of downtown. Again Biscayne Bay. There are fewer hills on this part of the sojourn, so relax, Lance. Pedal all the way to West Dixie Highway and head south through the Shores to 96th Street, where you turn left. Soon your car beckons. But you continue on to the dead end and settle on a bench in a pretty little park that looks out on -- you guessed it -- Biscayne Bay.
