Just an update: I got a ticket going down the hill mid-morning on a Friday in November 2009. The officer was in a Seattle Police Dept cruiser, pulled off in a driveway on the Uphill side of the street, about half way up the hill. I had just moved to the area and hadn't paid attention to the speed limit, but assumed it was 35 because it was a four-lane road. I found out the hard way that I was wrong when the officer whipped across four lanes of traffic and flipped his lights on behind me. I pulled into the parking lot of a business near the bottom of the hill, but before the light. He said I was going 42 in a 30, and I probably was. I hadn't had a ticket in over 25 years, and now I've had one a year for the past three years---grrr!
