Book excerpt: Author Heather Leigh guides readers on a spine-tingling tour through Florida's haunted roadside attractions. Florida roadways teem with amusements designed to extract a few bucks from weary travelers passing through. While most visitations are brief, some are eternal. Indeed, many of these Sunshine State amusements are inhabited by spirits who make their presence known. Blue beams ensnare tourists at the UFO Mecca that is Shoreline Park in Gulf Breeze. A bevy of specters can't stop performing for guests at the Ringling Brothers Museum in Sarasota. Visitors to the are advised to be on their best behavior when they happen upon the infamous haunted doll at the East Martello Museum in Key West--the doll, Robert, is known to bring misfortune to those who disrespect him.
