The Bird Herd

If I leave here tomorrow
Would you still remember me?
For I must be traveling on now
Cause there's too many places I've got to see
--Lynyrd Skynyrd

A while back a friend and I were standing on a train platform north of Chicago waiting to catch the El downtown. Across the way there were a couple dozen pigeons perched on a rooftop. Suddenly, one of the birds took off and the whole flock followed. They circled over our heads to the left, then around behind us, then to our right, before finally coming to rest...on the same rooftop that they had vacated less than a minute earlier.
