If I remember correctly, that play tower was added in 1984. The original, 1980 version of TSL consisted of the ballroom, a cable slide, and a play structure that sat where part of Riverblast's channel noww is. An animal petting area was installed in 1981, I think. It sat where part of the queue area is for Riverblast. Behind the Wagonworks barn...the big barn where Santa visits with kids this time of year. It was in 1984 when the barn, which was for special events and the boxing show, was converted to part of TSL. There were paper and leather crafts for kids in there, later the carousel was placed in there, come to think of it, that might have been in 1984, too. I was only on park as an employee for 3 weeks in August, '84. It blew me away how much they had done in the Riverfront area over winter.
