The only real intriguing thing you said after having mentioned it and asking if you knew where, was Port Huron, which is on the Detroit side the map. Personally you should start taking screen shots of what you are seeing and saving them, especially if they are setting up trailers near large cities with considerable concentration of homeless people....not that I think they plan on housing them, but I just know Trump isn't going to put billions upon billions solving the homeless crisis and they are sitting ducks out in the streets, prime targets should things take a hot spin towards his supposed deportation measures. There's other stuff, but I don't want to be going on, and on right now.
