I made this graphic early last week, or actually, maybe it was during my first week. In any case, they finally ran the story, and my graphic is on the front page of The Times Online (as of 1:39am Eastern time).
You can read the article. It's pretty interesting. In a nutshell, prisons are getting crowded, so states are shipping inmates to out-of-state private prisons. For example, California is sending prisoners all the way to Wheelright, Kentucky.
