Years ago, a buddy and I were driving around some pretty desolate roads in Florida close to the Everglades National Park. It was late at night, pitch black, and we hadn't seen any signs of civilization for almost 30 minutes. Coming around a corner, out of nowhere, we see someone walking on the side of the road. We thought this odd so we pulled over to talk to the person. It was a young girl, couldn't have been a day over 18, walking barefoot in the middle of nowhere. We asked if she was ok, and offered her a ride. She seemed slightly incoherent, but she politely declined a lift. We drove on and several miles later, after starting to rain, we found a crossroads. We determined where we were at on the map, and realizing were still a long way from anything, decided to turn back and ask the young girl again if she needed a ride. Went back to where we thought she would be and couldn't find her. Drove several miles further, still no sign of her. By this time it had started to rain hard, turned around and headed back towards our original destination and still didn't see her. Nothing along this road but trees and swamp, didn't pass any other cars, didn't see any other people, no lights anywhere but our headlights. Went to the closest town (don't remember the name) and called and told the local police. Still wonder to this day what happened to her. Would have thought I was seeing things had my buddy not seen it also.
