Snowbirds, amusing to Key West residents, since by far most of us were snowbirds prior to taking up residence on this island, illustrate how we were when we first came to Key West. Those arriving from New England are baffled by the unique lobster here in our warm waters. Upon raising them from the deep they are shocked to see there are no claws ... and they somehow feel short-changed in that they are more an appetizer than an entree. Huge New England appetites are immediately disappointed. They must not dismay, however, because as they ply the streets and boulevards of this paradise they will become intoxicated by selections available to them in the way of gourmet snapper, fish and chips, conch delicacies, key lime pies and groupers. Today's Yankee ... by God, is tomorrow's Conch!
