CHEYENNE, Wyo. (AP) — An old case of sibling rivalry could spell trouble at the AARP National Spelling Bee in Cheyenne on Saturday.

The bee is open to anyone age 50 and older, and it's very competitive. The winner typically has put in many hours of preparation by studying the dictionary.

The roughly 50 people signed up this year include four siblings: 67-year-old Joan Risley, of Arizona; 62-year-old Roger Risley, of Washington state; 60-year-old Chris Wagner, of California; and 57-year-old Prudence Hopkins, of Virginia.

The four grew up in an academically competitive environment and say they're not just having a reunion, they want to see who's the best speller.
Last year's winning word was "uakari", a species of monkey. Fifty-eight-year-old Tony Johnson nailed the word to win $5,000.
