I don't live in VA, but here in Indiana the law does not specify whether you open or conceal carry your handgun if you have your LTCH. In all the years that I have carried, I would say that I split my manner of carry 50/50 between open and concealed. I have never had anyone question or even give me a disapproving glance while open carrying, but I have heard of some folks being harassed by the police for doing so. It really seems that it boils down to your look, age and demeanor, whether you get noticed in a negative way. I am 47 and have a professional business appearance most of the time. If I were far younger, thuggish or acted skittish, I might attract a lot more negative notice of myself.
I don't know if that information helps in your situation, but if you do decide to open carry, you may want to look and act the part so as not attract bad attention.
