If you're a fan of farmers' markets, don't miss the granddaddy of 'em all. North Market hosts its 20th Farmers' Festival on Saturday, Aug. 13. The middle of August is reserved for the event each year because it is considered to be the prime of Ohio's growing season. Enjoy fun and freshness by the bushel. In addition to a plentiful array of fresh produce, there'll be contests including who makes the best homemade jam and jelly, or who grew the ugliest tomato! Also scheduled: a chef challenge, cooking demonstrations, live music and kids' activities. Event: 20th Annual North Market Farmers' Festival Place: North Market Date: Saturday, Aug. 13 Opens: 8 a.m.-4 p.m. (Free North Market reusable shopping bags for the first 500 customers!) Free! -Kristen Maetzold
