Dennis, I saw your advice about swimming from Florida to Cuba and back, I would say this: If the jellyfish stings and shark attacks don't get you on the way to Cuba, Castro's firing squads might be a definite inconvenience when attempting the swim back to Florida. Anyone with PD who attempts such a feat, would definitely get some attention from the media, so I would suggest he/she carry a large ball of string and a Udall poster on the journey, to take advantage of the coverage. :-}
