I do live in CA, but I’m from an industrial city similar to Detroit that ends in “burgh” (note the “h”)
In the past year I traveled to Detroit (Rochester Hills) quite a bit. My co-workers were making fun of the fact that I had to go to Detroit, but I was pleasantly surprised when I got there the first time.
I have lived in CA for a long time though. I guess I picked up the habit of putting “the” in front of road names.
