Just a warning for those visiting the US - crosswalks will only give you a false sense of security in many parts of the the country (bigger cities possibly excepted), many drivers pay 0 attention to them. Had a car narrowly miss me last week in a crosswalk, and honked at me as it whizzed by. I've never witnessed any enforcement of these kinds of violations against the drivers, either.
This is one of the many things I miss from cycling when driving a car: being able to just match speeds with someone else and hold a conversation over something that happened.
