Well we only had 3 cities until an area west of Richland started building up and then incorporated into a city a few years ago.
My daughter and SIL went to Calif a few years ago and on the way home she had to go to the bathroom REAL BAD so they pulled off the freeway into a gas station in Oakland. Predominantly Black area. She jumped out of the car ran to the bathroom and it was locked. She dashed to the front asked for the keys and the Black guy asked her, “Do you know where you are”? She said; “Yes, Oakland” He said; “You don’t want to go in there.” “WHY?” He said; Because they shoot up in there and killings happen in there.” “You best be leaving here.”
Yikes! Really nice of him to warn her
