3. You get a cool T-shirt. The Butler County Donut Trail is aiming to attract people to take the tour again (or for the first time) by launching a new T-shirt each year.
4. National acclaim for Butler County. More than 4,700 people from 39 states completed the trail in its first year. "It's great that we have something that's so unique and countywide that brings more attention to us as a region," Kocher said. The Donut Trail also made it onto national TV and statewide print publications.
5. You don't have to finish it in 1 day. Of those who completed the trail, 43.4 percent did it in one day and 19.3 percent completed it in just two days, according to the UC study. But there is no time limit to complete the trail, Kocher said. "Some take weeks or even months to make the full circuit," she said. "Many families or groups choose to explore one new location each week."
