I've been riding buses regularly for years now, and I still enjoy it. When I started, I rode local routes and was interested in the express routes. However, I mainly ride express routes to UW and enjoy local routes more. It's gotten to the point that I associate certain experiences with certain songs in my collection, because I listen to music on the majority of these journeys.
My local authority, Community Transit, has many routes covering a large area of Snohomish County. Just today I rode the 270 to Gold Bar and the 280 to Granite Falls. I've found that I really like those mountain towns way out there.
