While at Miami Beach we took a day trip drive to the Everglades. We saw an alligator from the safety of a boardwalk, and various birds – and were attacked by the most vicious mozzies (even through the repellent). When we stopped at the Royal Palm Visitor Centre and boardwalk, we had to cover the car with a tarpaulin (provided at the centre). Apparently the vultures have taken a liking to rubber and will sometimes pick at windscreen wipers, door rubber and tires. Luckily the hire car survived intact.
Definitely more to explore here than can be seen in a day. Our fancy to ride on an airboat (Gentle Ben style) had to be saved for another visit.
