Pinhook Rd in Lafayette is one of the busiest roads in the Hub City. Countless motorist travel the road everyday and just like me, never really give any thought as to why it's called Pinhook Rd. What is a Pinhook? Is it the last name of an Acadiana dignitary from the past? Well, turns out the origin of the name "Pinhook" is a bit of a hot mess...and a slight testament to good ole Cajun ingenuity.
