Seven Chipotle locations around town will be donating 50 percent of today's proceeds to Denver Bike Sharing, the Colorado nonprofit that operates the infamous B-cycle stations. Here's how it works: Stop by the Chipotle at 1480 16th Street in LoDo, 1600 California Street, 550 Broadway, 140 Steele Street in Cherry Creek, 333 East Alameda Avenue, 2500 East Colfax Avenue or 1644 East Evans Avenue (the very first Chipotle in the country!) and order your grub. Tell the staffer that you're there to support B-cycle, or just hand over a print-out of the flier below. For your troubles, you'll get a free B-card worth $5 off a 24-hour Denver Bike Sharing membership.
