Join us for a fun ride from Jack Block Park in West Seattle to Bicentennial Park in Tukwila and back. We will ride the Alki, Duwamish, and portions of the Green River and Interurban trails. Bring money for a fastfood lunch. This will be a lot of fun. Hope to see you there. Please be at the start by 09:50 am to sign waiver and hear safety briefing. Steady rain cancels.
