University of South Dakota makes embarrassing grammatical error in bragging billboard
This bragging billboard proves modesty is always the best policy.
The billboard along Interstate 90 west of Sioux Falls has a misplaced apostrophe in the word "Dakotas," making the word possessive rather than plural.
A USD spokeswoman says the mistake was human error -- the wrong version of a design was sent to the billboard company. The billboard is now being replaced.
