You have hot chips on the picnic table and the whole beach knows. Ibises, seagulls, pelicans and magpies push down four lanes of sand toward the chips, and all you have is one power board. A leaf blower gusts one lane, a pinwheel fan blows across lanes, and a floor fan throws a headwind that slows everything walking into it, but they all share one power board, so cover the whole beach and everything wheezes: the game is choosing which four or five towels deserve the pressure. Every bird shooed off charges Dad, and when Dad has had enough he clears the beach. Wave eight brings the emu.
