I want to know the answer to the following question:
What organization said Oklahoma's centennial was the top event in the US that year?
All the background I'm provided with is that "Oklahoma's centennial celebration was named the top event in the United States for 2007 by the American Bus Association, and consisted of multiple celebrations saving with the 100th anniversary of statehood on November 16, 2007.". Is that enough to answer the question?
Answer: yes
