It matters. My example is the thin divide between Alameda and Oakland, which is separated only by bridges and a tunnel. Oakland’s side near the bridges and tunnel is a s***hole. Cross over and you have Dick and Jane communities less than a mile away. The same with the barrio part of Redwood City that borders Atherton, which is a super rich city in the Bay Area Peninsula.
In the coming year this community will need military grade defenses.
Isn’t it amazing? You go through the tunnel and it’s like a whole other world. Of course the bay views also help
