Jim Denio (with mic), with his son Ken behind him, at an auction in 1968. Denio's grew from a single fruit stand in 1947 into a farmer's market, auction and swap meet open on Saturdays. Denio's today stretches over 70 acres in Roseville and is open year-round Fridays through Sundays. Nick Stasuc has been running a produce stand at Denio's Farmers' Market and Swap Meet since 1986. Adam Karapetyan, who has been selling leather goods at Denio's for 13 years, credits the open-air market for all his knowledge of the retail business, creating the foundation needed to open his own store, Bikerwear US in Folsom, four years ago. Milly Stasuc runs a second produce stand within the farmers market.
