“A few years ago, a group interested in building the Arts Community started a campaign asking folks to put a simple letter A in their home’s window. The idea was to announce your support of the Arts to those that lived around you. Our idea is not that much different. What we are hoping for is that you click this link, download the simple B (one for you and one for a friend) and place it in a street-side window of your home or place of business. Our expectation is that once this little idea makes its way around the country, we’ll hopefully grow the idea of riding a bike.”
