Sign Post Forest is famous all over the world. It is located in the town of Watson Lake, Alaska. This attraction was started by Carl K. Lindley, who was working on the Alaska Highway in 1942 and put a sign that pointed the way to Carl’s hometown. His idea was followed by others. There were over 65,000 signs in Sign Post Forest back in 2008. People erect up to 4,000 signs every year.
