Goose Island hiding free bikes across Chicago for '312 Day'

CHICAGO (WLS) -- A local brewery is running a new promotion that involves giving away free bicycles around Chicago.

Goose Island Beer Company, maker of "312" beer, is calling Tuesday "312" Day because of the date, 3/12.

Since midnight, crews have been hiding bicycles in various locations around the city, one bike every hour, on the hour.

If you find a bike, you can unlock it using the code: 0-3-1-2-0 and it's yours to keep! The trick is finding them.

Goose Island has been posting one clue each hour on Twitter and Instagram. Happy hunting!
