While many states around the U.S. have released information to the public about the frequency and routes of trains carrying oil obtained from hydraulic fracturing ("fracking") in North Dakota's Bakken Shale basin, holdouts still remain. Why the delay? Homeland security concerns, claim some companies.
This past November I sent you an invitation to visit North Dakota, and it seems you have taken up the offer. As I understand it, you will be visiting the Standing Rock Reservation on June 13. I hope you will consider visiting the Fort Berthold Reservation, what I would call Ground Zero of the Bakken oil boom.
