I'm going to the Cranberry Festival this weekend in Grayland... The bogs are a really neat site during harvest time. Grays Harbor Transit is giving guided tours for $1. "Bite of the Beach" is a chance to taste some regional favorites for as little as a quarter. Weather reports are calling for 62 and Sunny on Saturday.

I rate the cranberry bogs on the ocean right up there with the tulips in spring as a very unique-to-washington sight.
What other fall harvest events in Washington are not to be missed?
