We drove up to Washington (and flew back...one 14 hr drive with an 11 month old is enough). It was lotsa fun, here are a few things we did and saw.
We went to the Puyallup Fair (which my sister in law told me is the third biggest fair in the nation) and saw a horse show.
Then we drove to Rialto Beach. There was a storm in the '20s that washed up A LOT of trees, and the beach is covered in them. It is great.
