New Extreme Sleepovers at Ripley's Believe it or Not! Odditorium Museum Submitted by Swapna on Tue, 01/26/2010 - 11:49pm Have you ever wondered what is actually in the Ripleys Believe It or Not! Odditorium?

I didn't expect to care much for it, but found the experience surprisingly interesting. Find out more about this zany museum and it's special events: Read more.
