Biking in the city and throughout the urban area is becoming more prevalent and more managable each year. Indianapolis and Central Indiana are making progress in the development of signage, maps, lanes, and trails. Lagging far behind other major cities, Indianapolis is playing catch-up...but it IS working to catch up. As I become aware of resources for helping folks navigate Indy better on a bike, I will post the links in the right side bar of bikehiker.
One great resource for finding out about greenways, paths, and trails development in Indianapolis and Central Indiana is the Greenways Foundation. You'll find maps, project updates, and links to other efforts at http://www.indygreenways.org/.
