In my area, I see crows all the time, sitting on power lines and messing with posters on the street and so on. These are hooded crows and easy to distinguish from ravens. I see ravens as well, but not quite as often - though one of my local grocery stores has a small flock (murder!) of ravens that likes to forage in the parking lot. And to be fair, I live in a decently sized city of around 180,000.
one recent quote i heard on the bus: "ravens are near humans, crows are in the country"
