Slow Food
In 1999, Weaver founded Slow Food Central New Jersey as Slow Food International's sixth U.S. chapter. In August of that year, he held an event at Tre Piani called Har-Fest. Weaver invited chefs at local restaurants in New Jersey to offer free tastings of food made using local, seasonal ingredients. The event, which amassed a crowd of 500 people, included tomato farmers, cheese producers, beekeepers, and cranberry producers. The event helped convince Slow Food international to invest in the growth of Slow Food USA, which started in 2000.
