I live in a somewhat similar city in regards to racial composition and size. About a million people when adding all the neighboring counties which usually are considered as one area. My neighbor who is a longtime family friend and literally the individual who babysat me when I was a child (ie: very long time family friend) is the Postmaster General in the area. I bring this up because (and this is not an exaggeration, I mean this literally) every single postman/woman has recently been replaced with African nationals over the past, oh I'd say three or so months.
That is extremely odd for this area. Not in a "you're a racist" way but moreso that my family friend said it was ordered by the state (CA) and many postmen/women who previously had positions were "laid off" to make way for them. I have friends in neighboring counties who also noticed this as well and it reminded me of that threat we saw two years ago about foreign fighters being placed into FedEx, USPS, and similar positions for a coordinated attack of some kind (similar to what that Judge dealt with last year). It may not mean anything but figured I would bring it up since fellow anons are discussing a somewhat similar issue from Idaho with busses.
