This sounded familiar after reading 'Fright Zone' in your entry. By following the link, I see it's a Cedar Faire park. We have Cedar Point here that does the same Halloweekends thing. I'll have to consider taking the girls, it sounds like fun - and it sure looks like Charlie had a blast. That grin on the merry-go-rounds says it all! I like the 'say boo back' idea too - I'll have to remember that one for Holly, she gets so freaked out.
