You could try a run to Key West. Superb views of the keys the whole way down and an interesting approach at the end. Busy airport with heaps of GA and some line traffic.
Great place to stay for the night. Inspite of what they say the place was full of young chicks out enjoying themselves.
Did this trip about 4 years ago out of Winterhaven, fuelstop in MIA in a PA28. More fun in a twin I guess.
