Welcome to OCDO!!! Stick around and you will learn a lot.
I am from Springfield. I have been open carrying all over Northern Virginia for the last four years without incident. We have events pretty frequently and they are usually posted as stickys at the top of the Virginia sub-forum. And as aleays you can start your own event. Just pick a place and a time, post it here, and people will show up.
Good to hear that you want to start open carrying. If you would like to meet up for a quick lunch before the next event, PM me and we can set something up.
In addition you should check out the Virginia Citizens Defense League. It is a great group dedicated to gun rights in VA. If you go to their website you can sign up for VA-ALERT (on the right side of the page) which is a free email system that will keep you informed about everything gun-related going on in the state.
