New York City kicked off its very own vegan event-filled weekend of cruelty-free fun last night with Veggie Prom in Park Slope, Brooklyn. Veggie Conquest founder Jessica Mahady organized the prom, and also helped arrange the follow-up Vegan Prom Hangover Potluck Picnic happening today in Central Park. Organizers of the hangover picnic are encouraging people to bring a plant-based dish, musical instruments, picnic blankets, and friends to this relaxing, afternoon event. Tomorrow, vegans can march in the huge, third annual Veggie Pride Parade. Along with participating in the parade, there will be live music, vegan food, and a costume contest.
