Riders planning to join the annual horde of bicycles taking over one of Chicago's most famous roadways have less than a day to save some money on registration.
Organizers of Bike the Drive say Sunday is the last day to register before the fee jumps by $3.
There will be another increase for same-day registration.
The May 29th event offers hours of car-free biking along Lake Shore Drive, with a carefree tour of the Lake Michigan shoreline like no other.
Participants start downtown and can ride up to 30 miles. As many as 20,000 bikers have participated in the past.
