13 July 1976, Times Herald Record (Middletown, NY), pg. 7, cols. 1-2:
The so-called “Minnesota Strip”—a stretch of 8th Avenue between 42nd and 52nd Streets—was barren of hookers, pimps and convention delegates.
An area of cheap bars, massage parlors, porno book stores, peep shows and hotels of questionable repute, the “Minnesota Strip” got its name from a reported influx of teenage prostitutes following passage of tough morals laws in the Midwest.
