My good friend's younger sister is currently in North Dakota (and has been for several months), doing research for a book on the oil boom, which has caused a bizarre pocket of social and economic disparity. She is currently keeping a blog, which you can read here:

It's pretty interesting/horrifying stuff. Especially the ways in which the native residents have been affected, and the ways in which a very unbalanced male/female ratio and a lot of wealthy oil men leads to some horrific misogynistic behavior (I don't know if they cover it here, but I remember reading an article about men literally dragging a girl into their car).
