Bike Walk Wilmette, Wilmette’s active transportation advocacy group, hosts monthly bike rides on the last Thursday of each month April to November, a local version of Chicago’s “Critical Mass” rides. Join them for a 30 – 40 minutes group ride with a different theme each month. Meet at Village Hall. Riders of all ages and abilities welcome. Contact the group to be added to their newsletter list, to volunteer, or to leave a comment about biking or walking issues. Check out their website.
