Here is all the information you could ever want on Walnut Creek Park. http://www.albemarle.org/department.asp?department=parks&relpage=2744
I also am not getting the obsession with where the Command Center is located, seems like there are other things that could be focused on.
There's no "obsession" with the command center. During a crime scene investigation, a command center is set up on location of the body. Coy Barefoot provided a body location that is a couple of miles from where the command center is set up. I'd like to know where he got his information.
This is the command center (where all necessary equipment for crime scene analysis is kept) for Morgan's crime scene. It is at the body location, not a couple of miles away.
