Where can I get foreign currency exchange in the US?

I will be traveling outside of the US and was not sure if banks here will offer foreign currency in exchange for dollars, otherwise where can I get it?

1. At the airport, buddy. Foreign Exchange.
2. the easiest place to get it is at the airport of wherever you go--or a place that does it wherever you go.
3. foreign exchange or a bank. You are guaranteed to be able to change American($)dollars or Sterling(£)pounds in any country in the world
