What kind of things do you want to see/do? City, country? Indoor, outdoor? Eat, watch, walk, listen, etc??
Um... all of those things? I don't know. Outdoors is great, but I'm afraid rain might keep us from too many of those types of things. Music is probably last on the list, simply because my husband and I could never agree on what type of group to go see.
Walking/seeing things mostly, I guess. And eating too... I have very fond memories of the Boeing factory tour that we took when I was a kid, do they still do those?
