Things to do in Seattle Sunday Morning?

Travel Info
I am going to be passing through Seattle and have a little less than 1 day there. What kinds of things can I do in Seattle on Sunday morning? Looking over previous answers, I saw people recommended Pike Place Market/1st Starbucks, and the Underground Tour. (I've already been to the Space Needle and EMP). Are the market and underground tour open Sunday mornings? Are they good rainy day activities? Any other suggestions I'd be able to fit in before 2pm? I'll also be there Saturday night, but I'm not that interested in nightlife. Are there some pretty things to see at night? I'll have a camera and tripod with me. Thanks!

Travel Tips

Walk around Green Lake (3 miles), or have coffee and rolls at the Madison Park Bakery (see below) or take a round trip ferry boat ride (walk on), or watch boats go through the Ballard locks, (most of these afford good photo ops and pretty views) Source(s): http://www.madisonparkbakery.com/...

you could go to church!!
I really enjoyed the boat tour which departs from the Pier area behind the market, then circles around the locks to Union Lake. We saw the city from the water, the tower, salmon at the locks, several suburbs on the water, etc...pleasant .... Tour name is Argosy, link below:
