Well how much fun you are going to have....and, yes, there will be a whole bunch more photos coming, and they will be better than the ones I have up.
Must sees for seattle.yes, there are many. There is of course, Seattle itself. Visit the Space Needle, and go to the top. Pike Place market, all of the piers with stuff to do for the whole family. Dont miss the underground tour of Seattle, as it is a city built on an older city...(not too many people know about the underground city) All of these items are in walking distance in Seattle. Outside the city...there are a few really neat scenic drives: One is to the town of leavenworth, a Bavarian town high up in the cascades off HWAY 2, its about a two hour drive from Seattle. One of our favorite day trips is a ferry ride from Mukilteo (about 20 minutes North of Seattle) to Whidbey Island. This 27 mile long Island has a lot of neat sights. A winery, and the artist town of Langley. (The best meal in the state of Washington is dinner at the Inn at Langley reservations a must.) from there, you can continue North through Deception Pass State Park, whith the highest bridge in Washington, and views to die for. That bridge brings you off the island, and into Skagit County, a farming community with alot of charm.
If you want a few more details, or want some really coo specific places to go, let me know what kind of stuff interests you, and I will tell you ALL of the must sees!
I am excited you are making a visit here...we have loved this states treasures!
