I lived in Colonia growing up and headed down the Parkway or Route 35 to hit the beach every chance I got.
What I always marveled at was that you could be no where near the Parkway and there was always a sign pointing you towards the Parkway. Certainly made me confident exploring new areas without a map because there was always a Parkway sign to get me home.
Who are the mad Parkway sign planters? They did a great job!
