Normal Roundabout

While searching for information for another project, I ran across a brochure describing how to use a roundabout in Athens, Alabama. It seems that Normal isn't the only town educating citizens about this new-fangled type of intersection. I would be interested in seeing how many roundabouts are being built or planned for cities and towns in the U.S. If they are becoming more popular, maybe it’s because drivers just don’t want to take the time to actually stop at stop signs (or red lights) any more. Gotta keep moving on!
