As the little sister of the long-lived and perfectly run Horseshoe Market in Berkeley (winner of numerous past Best of Denver awards), the Jefferson Park Farm & Flea is still growing into itself after its first full season of mixing up the best in open-air local-produce shopping among a curated selection of craft and flea vendors. But there's no doubt that market founder Amy Yetman's concept is a good one, from its placement on the street in a changing neighborhood looking for an identity to its emphasis on keeping the world small by supporting local businesses and encouraging people to pitch in and help one another. When the market opens again in May, urban farmers will be invited to bring donations of excess produce for area food pantries. In return, contributors will be awarded with discount coupons good at market vendor booths — and that's just one example of how Yetman is making the world a better place through conscientious marketing. This year's JP Farm & Flea will run monthly on second Saturdays from May through October.
