"The Center of the Universe in Tulsa is an audio oddity. For reasons that scientists don't entirely understand, those who stand on this point — marked by a worn, circular stone at the center of a pedestrian bridge downtown — can speak as loud as they want and not be heard by passersby standing even a few feet away. So go ahead and loudly proclaim your love instead of whispering sweet nothings. No one else will hear." - Travel + Leisure Editors
