The Richard Nixon Library has a fire truck that was damaged on 9/11 and pieced of debris on display at the library. My family and I are going on saturday to see it. Though you all might be interested.
"Library to witness a stirring reminder of the terror attacks of September 11, 2001: the arrival of 20 tons of World Trade Center steel remnants and a New York Fire Department aerial ladder truck damaged during rescue efforts at Ground Zero."
