Clothing/Shoes/Weather Gear: Shoes- Unless you are going to be hiking at Pt Defiance, I suggest comfortable, closed shoes.
I also suggest a sweatshirt. I wear an Adidas zipup basketball sweatshirt. It is light, and I can put a thin rainjacket over it. I never go out in tacoma without my sweatshirt. Then again, I never go out in Victoria, Matsumoto, Tokyo, or Kuroiso without it either...
