Nets: D.C. Speed Bumps
 

Something collectivists do...I wonder how the graph would look? And the rate variation in added links?

"Since Adrian Fenty became mayor in 2007, the number of speed bumps in the nation's capital has jumped from 157 to 691. The Fenty administration has authorized twice as many speed bumps in 2 1/2 years as the Williams administration authorized in five."
