Oh and by the way to answer daedrans question no the slide and the cave no longer exist they were built specifically for the movie and like the sets from most movies they become a dead strike after filming is complete.....

p.s
a dead strike is the tear down and dispossal of a movie set upon completion of filming!

Speaking of the attic scene heres a little known fact-
when Mikey knocks over the picture and then picks it up so we can see who it is,we learn the story of Chester Copperpot Mikey says,"hes the original Goonie!"Well the man in the photo is Robert Scaife the construction coordinator,it has been told that when Steven Spielberg had came across that picture of Bob from a previous film they had done together,that he felt it was the perfect look.........
and I just know that Bob is smiling down from heaven over the fact that people are still speaking of a movie that was made so many years ago!!!!
