Mike - I'm actually about half-way between Key West and Marathon. I lived in Key West for about 6 years but it got to be too loud and too crowded. I lived in Marathon for over a year too, but it's getting ruined by some greedy developers. So now I'm down on Big Pine Key, where things are very protected because most of the island is a preserve for the endangered Key Deer. So my location really should say Southernmost Point minus 30 miles.
