Thousands of street rods, custom cars and restored vehicles lined the streets of the Minnesota State Fairgrounds during the Minnesota Street Rod Association's 45th annual Back to the '50s weekend, which began Friday. Only vehicles from 1964 and earlier are allowed in the show, and all vehicles must be licensed and legal for driving on the street.
