When it's summer in Miami, it's winter in South America. And that means the beaches of Rio empty en masse and a veritable bikini-clad army of samba babes fly north to oil and tan their buxom backsides on South Beach. The millionaire playboys who love them follow soon after, and before you know it, South American tourist season is in full swing with families of Disney-bound travelers stopping in Miami to buy cargo containers' worth of electronics to take home. For bartenders, store owners, T-shirt salesmen, body waxers, and party lovers, it's a boom time. And for fans of the beach life, it is too.
