VA Tour Mid-August

I am adding VA to my tour schedule in August and am looking into staying somewhere in Arlington, Fairfax, Tyson's Corner, or near Dulles Airport. Any thoughts on these areas as far as safety?

Thanks for all your help

I've worked in them all very regularly for a bit over 4yrs and would continue to. Safety is as well as you screen ... they are all good areas to me and feel safe working in them all.
