(Duluth, MN)  --  For just a few dollars, you can own a piece of a famous Minnesota landmark.  The City of Duluth is selling rivets for 12-dollars apiece from its legendary aerial lift bridge.  The rivets were removed last year during bridge renovation work.  Duluth spokeswoman Pakou Ly (PAW'-koo Lee) says each rivet will have a certificate of authenticity signed by the city's mayor.  About 600 of the rivets are for sale.
