Each year our readers choose A1A as the best scenic drive in Broward and Palm Beach counties and of course they're right -- in part. There are some scuzzy stretches of this oceanside road, to say nothing of the many miles of looming condos blocking that same ocean from view. But the stretch of A1A from the Flagler Memorial Bridge to Southern Boulevard (known to its Palm Beach residents as Ocean Boulevard) is truly scenic -- if your idea of scenic runs to the homes of the rich and famous. The route is lined with French chateaux, Italian villas, English Georgian, plain old American colonial, and the ubiquitous Mediterranean. It's a visit to the Wizard of Oz-tentation in his Emerald City of envy-green hedges clipped to manicured perfection and acres of velvety lawn (no drought in Palm Beach, folks). If all this splendor makes you grind your teeth, turn your eyes eastward. With the exception of an occasional gazebo larger than your house, the road is open to the vast expanse of the Atlantic crashing below the cliffs. Nature knows what scenic is.
