I was just there yesterday! Sadly, the system 80's were down (Black Hole and Haunted House). They were down last time I was there, just like they were always busted when I was young....... so nothing's changed! You gotta love that place. I don't know how they do it.
I think I would rather go on a week day when it's not as busy and Tim Arnold is in fixing the machines. I think he is amazing but I never chatted with him. He looks pretty busy!
