Men in Black (and white)

Who are these weird group of men all dressed in black shorts and white polos?
Who ride up on bicycles only to abandon them and walk off separably.
Never speaking.

They wonder around the park,
stopping here and there as if in thought;
Those execs who lost their suits.
Finally to gather around an empty picnic table.

Ah! A white van with out-of-state license plates pulls up.
Out come the coolers and food.

A short time later in twos and threes they ride off...
coasting downhill.
