We took off yesterday afternoon for an end of summer trip to the other Dash Point, not Dash Point State Park, but Dash Point Park and Pier, a city park on the Tacoma side of the point.
Getting there was nice, the kids napped in the car while Marine View drive turned into Soundview Drive and wove its way around the edge of Puget Sound. If you're wanting to squeeze the last few minutes out of summer, this drive is a nice way to do it. I don't recommend trying it around 5:00 though, I had some impatient people on my tail wanting me to speed up around the curves. (The speed limit seemed fast enough for me, there are some tight corners.)
