Next meeting in Annandale, VA this Thursday (Mar 15) at 7:30 PM
PM me if you are unfamiliar with Northern VA and want directions to the meeting or just feel uncomfortable open carrying in general. I live in Annandale and would be happy to meet you somewhere (in Annandale) to take you to the meeting place which is a police station (while open carrying).
