Summary: Ahead on this edition of Ozarks; startup companies end a more-than-three month acceleration process and vie for $150,000 prizes to be used as investments in their new companies. The first-ever ARK Challenge ended yesterday at Crystal Bridges in Bentonville. And, this is a time for anniversaries in the area: 20 years of Walton Arts Center, one year of operation at Crystal Bridges Museum of American Art . . . and 20 years for one local store that has grown thanks to the web.
