Reminds me of my trip to South Korea this spring. The older guys who had been there before (including ex-military who had been stationed there) told me that if you ever see a large crowd gathering, don’t hang around to see what it’s about, get the hell out of there. Another thing to look out for is a large gathering of police. If you see either of those two things, rioting, flying molotov cocktails, tear gas, and cops swinging billy clubs at anything not wearing a uniform is soon to follow. Not good.
