hey,
i too am 20 and are pretty sure that it shut down late 2001 when i was 13. i remember for a short time you could walk around up there just after it had closed to use the toilets and it was so sad as it was just all dark and a mess. most rides had been taken out and the place had lost its character. these days it's just not the same and i always reminese the fun times i had as a kid whenever i go to the movies.
