Here's info I got from metromix.com:
Ride 25 moonlit miles through downtown and North Side neighborhoods for the 16th annual "Long After Twilight Ends" recreational ride. Snacks and a post-ride breakfast at Buckingham Fountain provided.
Participants gather at midnight at Buckingham Fountain for live music, free Frappuccino samples, "best lit bike" and "best decorated helmet" contests, registration and packet pick-up.
Neighborhoods include: Greek Town, River North, Lincoln Park and more. The ride starts between 1:30-2:15 a.m. and goes northwest to Foster Avenue and Pulaski Road, then east to Foster Avenue Beach and south along the lakefront path back to the fountain. Registration is limited to 10,000 participants.
Jul. 11: midnight live music, registration and packet pick-up; 1:30 a.m. first wave of ride begins
So if you want to crash, there's the route! Have fun!
