Who says it’s wrong to play with your food? At CORNucopia, a new Historic Hudson Valley festival at Philipsburg Manor in Sleepy Hollow, you’re encouraged to do so. You can take part in a corn-husking contest, navigate a kid-sized “maize maze,” or help make a corncob mural. Of course, you can eat some, too—or try a taste of some stiff corn whiskey. The corny festivities take place from August 31 to September 2.
