Just a quick little cache. It is a small mint tin, that is colored the same as the suroundings. Have a seat and take in the view of a actually pretty neat building, and then walk up the stairs and look at all the great landscaping.
You can see it from the top of the seat, but with the GPS bouncing around this could be pretty bad, I had to use satellite image to figure out the right coordinates.
There used to be a realy cool dragon art near by, I'm sad to see it is gone now.. I think i have a pic, maybe that will help you.
After, there are stairs to the west, that you can walk down, and get a close view of Boeing, and then walk out to the water front and take in the view. I have walked this a few times, and highly recommend doing it right around sunset, it really makes it all the better.
There are plenty of parking spots near by, but I'd say park at Coulon Park, also get the Adventure Labs and the Werigos there too.
Anyway... Happy Caching and Keep Adventuring!!
