oma-dome

This is the invisible dome that surrounds the city of Omaha. It keeps bad weather out of the city and it is the real reason we never get snow days. The oma-dome is operated by a man in the mayors office whose sole mission in life is to press the button allowing the dome to descend upon the city. The dome is invisible, can be passed through with absolutely no resistance and is a one-of-a-kind.

Person - "yay! its supposed to snow tonight!"
the next morning... no snow
Person - "darn you, oma-dome!!!!'
