Carowinds is a 398-acre amusement park, located adjacent to Interstate 77 on the border between North and South Carolina, in Charlotte and Fort Mill, respectively. The park opened on March 31, 1973, at a cost of $70 million. This was the result of a four-year planning period spearheaded by Charlotte businessman Earl Patterson Hall, who was inspired to build the park by a 1956 trip to Disneyland and a dream of bringing the two states closer together. It is owned and operated by Cedar Fair Entertainment Company. Boomerang Bay is a 20-acre water park located within Carowinds's 398 acres and is included in regular park admission. ... more on Wikipedia
