Ahh, South Florida. Sun, sand, surf, and shade. Shade? OK, so South Florida, with its wide-open beaches and signature palm trees, isn't exactly renowned for offering lovers of the outdoors much natural relief from the heat -- which is just one of the things that makes a milelong stretch of State Road A1A through the tiny, tony town of Gulf Stream so, well, cool. Along the stretch just north of Delray Beach, drivers and bikers are shrouded by a canopy of spectacular Australian pines that line the oceanfront highway. Can you believe that, if state transportation workers had had their way, the 400 trees would be gone? For years, well-heeled town residents fought to save the 80-year-old trees, which are on the state's hit list because they have a tendency to blow over during hurricanes. In 1996, in response to residents' appeals, the Florida Legislature finally passed a special law that protects this swath of trees from state chain saws in perpetuity. State road officials and environmentalists, who hate the trees because they're not native and crowd out vegetation that is, are still upset that the town won the war of the wood. But when it comes to stuff along the shore that crowds out natives and has a tendency to fall down during hurricanes, trees sure beat condos.
