back to the beach . . .

. . .   back to Sandy Beach on this glorious day.  Tradewinds have returned, the water is sparkling, sun shining brightly, high 80sdegF. 
No worries, that's a swim fin, not a shark!  
Clearly a hand is needed (extra 1), the hair stands alone ! (extra 2), and (extra 3) I'm calling 'chicken, chicken' - both guys on the wave are aware of the other guy, but below them, two guys are starting to dive under.   Which wave guy will pull out first  . . . ?   (don't know the answer to this one, don't ask me.  I just takes 'em like I sees 'em.)
