I have loved looking at all these pictures Pintrader! I only know sdc from 1987 on, so anything from before that time has always intrigued me.
In my mind I can remember Huck Finn's Hideaway from the late 80's-early 90's, but wish I could see some pictures of it on the inside from that time and before. I remember the window's you could 'shoot' the guns at the long johns hanging in the trees along with the green-screen that captured your shadow when the light flashed. I wish I could remember some of the other gags, I'm sure there were more. I remember climbing the 'tree' staircase with my dad and crossing the little swinging bridge. Later they added netting so you had to cross it on your knees, at that point my dad said "Nope." The only way down during my childhood was the back staircase. But apparently at some point there was also a bridge that took you to a little door located in the Toy Shop (now woodcarvers), the door is still there if you know where to look.
