Thanks All!
I will stay at the civilian campground. A couple of posters have made the point that because this is really about work, I should probably put connectivity higher on the list of "must have".
My biggest concern about the park in Clarksville was safety and its proximity to an active junk yard. I am good with noise. After 28 years in the Army, rifle, shotgun fire, and helicopters can lull me to sleep!
My other concern with the Military campground is the weight limit on the bridge. I was "told" the sign was put up to stop commercial truck traffic as opposed to an actual weight limit. That said, I *don't* want to be that guy who collapses a bridge! I would have preferred to stay on post (old habits), but the lack of signal will really cramp my ability to communicate.
Thanks again!
