"...Downtown Sandusky was designed according a modified grid plan known as the Kilbourne Plat after its designer. The original street pattern featured a grid overlaid with streets resembling the symbols of Freemasonry.

Hector Kilbourne was a surveyor who laid out this grid in downtown Sandusky. He was the first Worshipful Master of the Sandusky Masonic Lodge. Sandusky is the only city in the world originally laid out on Masonic symbols."
"When Cedar Point's white sand beaches made it a popular vacation spot in the late 1800's Sandusky's population grew even more rapidly."
