About 10 years ago, a local motorcycle group with Uptown Columbus began 'Bikes on Broadway'. It was a way to get locals back to the uptown area as an entertainment option. I wouldn't call it a festival as it is still relatively small, but I am sure it will continue to grow.
This vignette was set up specifically for photographers. They really should have put the orange vest away tho.
As a side note, this is 9-11 and the flag shot seemed appropriate.
