In 2002 I rode in the Cascade Bicycle Club’s (https://cascade.org) Seattle to Portland Bicycle Classic in one-day. I rode it on my (at that time) new LeMond Tourmalet road bike.
The photo was taken just north of Centralia, Washington on SE Bucoda Hwy (SR 507). It is close to the STP half-way point, about 100 miles into a 207-mile day.
