By the way when EDB'S and Pygmy's first occupied the Keys it is likely there was perhaps a land bridge and if not certainly there was NO OVERSEAS HIWAY WITH 12,000,000 CARS A DAY DRIVING DOWN THERE. The very fact this road and the millions of people that travel on it day and night create a TREMENDOUS BARRIER against colonization far more effective than almost any natural barrier might. Just drive to Key West once and you'll comepletely understand...
