Second City Scooter Society ride around Lake Michigan to New Buffalo, MI.

From the Facebook event page (check there for updates and details):

Ride around the south end of Lake Michigan to New Buffalo, MI to dine at Stray Dog , then stop at Beverly shores to dip your toes in the lake or to take in the 5 futuristic (by 1933 standards) homes transported there after the second Chicago Worlds Fair. Meet in the driveway of La Rabida hospital.
