There will be a lot of US there, there will be large groups of US in a single location. My Advice, spread out all over DC. Do not congregate in a single location. Stay away from neighborhoods. But this link says it better than I can. https://youtu.be/X-bogN0V8RM?t=68 exactly where the video starts. Stay Alert, Stay Alive, 360 Awareness, keep loved ones close, and if shit hits the fan, rally together and stand as one. For every person who runs away is just an easy target and large groups of people in a single spot sounds like a jihadists wet dream.
