I live near Gig Harbor, previously near Seattle. The Seattle area paved trails, like Burke-Gilman, Sammamish River, Centennial out further east, are great. Here in the southern Kitsap Peninsula it's more traditional country roads - narrow, few bike lanes, with plenty of big trucks. Most drivers are courteous but some are downright dangerous, speeding while passing cyclists on blind turns, running them off the road, etc. When I lived on Orcas Island it was similar, narrow roads, but the drivers were much slower and safer. They're on "island time".We are clearly neighbors. I'm in Sammamish. I love the Centennial Trail. I rode part of it yesterday as part of a longer ride. My commute is mostly on the Sammamish River Trail and then low traffic surface streets. The SRT and the other trail systems in KingCo can be very busy in summer. In winter, it is a different story, but you see more wildlife on the trail. I saw a cougar once on the SRT. It certainly pushed my speed up quite a bit!
As an avid road cyclist for over 40 years I have high tolerance and don't hog the road, courtesy goes both ways, but I've had to take down a couple of license plate numbers since we moved here.
