For the 31st year, the Street Rod Nationals North show brings as many as 2500 street rods to the Kalamazoo County Fairgrounds and Expo Center September 8 - 10, 2017.

Jim Rowlett, marketing director for the event, cites the official definition from the National Street Rod Association as "a modernized vintage vehicle that must be of pre-1949 manufacture". The vehicles are equipped with the latest options, like cruise control and air conditioning, among other amenities.
