On the drive from Anacortes, Washington, to the Madrona Fiber Arts Retreat in Tacoma, wending our way through the back roads of the Skagit Valley we ran across a wondrous sight:
Thousands of snow geese. 40,000 of them according to the self-described "goose and tulip obsessive" photographer we questioned. They make a stopover here most every winter, migrating between Eurasia and North America per Wikipedia.
As we stood by the field some silent signal passed between the birds and they rose in a great cloud over our heads, to settle in a distant field.
An amazing experience!
