Someone mentioned in the comments that they saw a CaBi bike around yesterday, and BeyondDC snapped a photo of one.
If you see one today, you could win a hat.
The first Capital Bikeshare bikes will take their first tour of DC tomorrow (Friday). Spot one, snap a photo, post it here or tweet to @DDOTDC. We'll pick our favorite photo and and you could win a limited edition hat!
The system will open with 30 stations in September.
