Dozens of Austin carts, trailers, vans and push-carts together in one spot for stroll-around tastings and, of course, live music. Organizers also are planning a cook-off to crown a fan favorite and other awards. Admission will be free, with food for purchase from each vendor. The event is being put together by the C3 team of Austin City Limits Festival fame and Tiffany Harelik of Trailer Food Diaries. Details at www.gypsypicnic.com
