I haven't lived in West Chester/Pisgah since 1990, but yes, I think that is where it was. Really close to Mason, probably less than 15 miles.
As I have pointed out before, Congo is also basically the same equipment as the old Jurassic Park ride at Universal Fla, just with more than a lift hill followed by a drop. Bush Gardens had one as a large dark ride. Seems to me like they dropped the ball on Congo.
