Hi

To answer this question, it is helpful to know something about the Key Bridge:
http://en.wikipedia.org/wiki/Francis_Scott_Key_Bridge_(Washington)

The Key Bridge spans the Potomac River and basically connects the US state of Virgina and Washington, DC. So the boy is in the river near the Key Bridge, close to the Washington, DC side of the river.

thank you so much, now i think that learning more about geography is a useful way to listen better.
