“Why were they there?”
Well, it was a pretty day, a bar that specializes in attractive waitresses and which had a giant sign saying “welcome bikers for bike weekend 2:1 drafts.”
2 easy questions;
1. Have you ever been in an establishment (bar, restaurant, mini-mart, etc) and about 100 obvious gang members come in?
2. Did you stay?
If the answers are yes, no - then you’re part of it or suicidal.
If the answers are yes, yes, then you’re smart enough to not put yourself in that situation.
I bet the answer to #1 is no, which would mean that you have very little experience with any type of gang element.
