After a rough summer following the BP oil disaster, the Westwego Farmers and Fisheries Market (484 Sala Ave.) wants to share some fun and levity with its visitors. The market hosts a Halloween costume party on Oct. 30 and will have pony rides, clowns and face painting from 8:30 a.m. to 12:30 p.m. After the inevitable post-Halloween crash — following all-nighter pumpkin carvings, visits to haunted houses and candy binges — a dose of healthy activities is in order. Families can send their children to the Crescent City Farmers Market's Marketeer Club, an event on the first Saturday of each month with healthy eating activities for children under 14. Kids can bake pizzas, churn butter, talk to vendors and receive birthday surprises. Visit www.crescentcityfarmersmarket.org to sign up. The Westwego market kicks off a Friday night concert series starting at 7 p.m. Nov. 19.
