Welcome to LA! Conan's O'Brien's legacy is complete. He's written for David Letterman, leap frogged him to the Tonight Show slot and now... He's canoed the L.A. River also known as the L.A. storm drain (concrete flood control channel).
The river was paved over in 1939 and has become an eyesore ever since. It's well known for scenes in films such as the hot rod race in Broadway musical turned film, Grease.
