Carowinds

Carowinds is a 105 acre theme park, located on the borderline between North and South Carolina, in Charlotte and Fort Mill, respectively. It opened on March 31, 1973 at a cost of $30 million, after a 4 year planning period spearheaded by Charlotte businessman Earl Patterson Hall, who was inspired to build the park by a trip to Disneyland in 1956, and a dream of bringing the two aforementioned states closer together.
