You say you know about the Everglades.... money an issue, etc. I am a Fla. native and much-time tourist in this "boring" state (per previous poster). Been everywhere, many times over. However, until about 3 years ago, I discovered a MAJOR NOT-TO-MISS. We had never taken the guided tram ride in Everglades National Park in the area called Shark Valley. 14-mile round trip, but we do it on bikes instead of the tram. Absolutely the top pick all over the South Florida area for us. There are bike rentals there (we bring our own). The tram guides are excellent. We fly past all the tacky Seminole Indian airboat concessions down Highway 41 and head straight to the unspoiled National Park. Gators like logs lying around everywhere. What a kick and cheapo to boot.
