Thanks on behalf of afewgoodmen - it's taken eight weeks but nice to have a solution to one of the many little speedo mysteries which crop ( and is coincidentally from South Beach at which I could only find a boring rollerskater for the Miami thread - so Louis was right).
It does of course look posed rather than a casual action shot of a real lifeguard but did you capture it simply as a passer-by or as a professional photographer commissioned for a particular commercial photo-shoot?
