Thank you for pointing out that you have no idea for yourself. As I stated, you personally do not know and are merely quoting someone else that as far as you know is not entirely correct. I believe that if you were to check his references it would indicate that he is talking about where rivers pass through major metropolitan areas.

If a river were indeed bordered completely by concrete, then it would be man made, and not truly a river then would it?
