Hesitatant wild geese hold up airport-bound traffic

Summer evening. On the approach to the Vancouver Airport, A handful of Canada geese crossed the highway in an indecisive fashion. Some turned back to look at their fellows, while others paused before changing lanes. All were quacking away among themselves.

Net result: fewer than a dozen geese brought three lanes of fast-moving traffic to a halt.

"Why are they walking?" my husband mused. "They have wings. Why don't they fly?"
