The annual Woollybear Festival is held every Fall in downtown Vermilion, Ohio, on Lake Erie. The one-day, family event, which began in 1973, features a woolly bear costume contest in which children, even pets, are dressed up as various renditions of the woolly bear caterpillar. The festival is held every year around October 1 on a Sunday on which the Cleveland Browns either have an away game or are not playing. It is touted as the largest one-day festival in Ohio, with attendance over 100,000.
