@SwampDonkey Before Tiger World opened, the grounds were home to a zoo called Metrolino Wildlife Park (aka Metro Charlotte Zoo). which closed around 2007. Not sure what the pool would of been used for back then.
@SusScrofa oooooh, I remember that place when it was called. I never went but I remember it being on the network news once when I was a kid on vacation in NC in the mid 90s or so.
