Bicycle Horns
I heard them before I could see them:
"Honk" "honk"--like someone
   was squeezing pink rubber bulbs
       behind gold and black horns.
I looked around and saw nothing.
   Then I heard the sounds again,
      directly overhead:
geese, not bicyclists were responsible
    for the sounds I had been hearing.
Moments later the bicycling geese were gone.
