I'm off to Seattle on Sunday for ten days on business. I've been there once before, so have done a few of the obviously touristy bits (Space Needle, EMP, market etc)

I'm planning to take a drive into the Cascades at some point, but does anyone have any recommendations for anything else I shouldn't miss this time ?

P.S. I also get to drive in the US for the first time, which should be fun, especially as I've never driven an automatic before...
