WOW! This series of photos truly knocks me out. NEVER have I heard or seen of this slide exit to the treehouse. My personal association with the attraction goes back to 1970. That means the slide would have been in effect only from when the treehouse opened in 1968, and in the 1969 season. I'd love to see more shots of this slide, and any shots of Grandfather's Mansion when it was "Slantin' Sams." Thanks Rube, for these photos!
