Durham, North Carolina, has changed a lot since its days as Bull City. The home of Bull Durham tobacco is now known as the City of Medicine, in part because of Research Triangle Park, which is anchored on one corner by Duke and North Carolina Central universities. And although the past remains important to locals, the area's entrepreneurial spirit pushes it into the future. In fact, many of the historic buildings have been converted to usable spaces for today's citizens. For instance, the Golden Belt, a former textile mill, now houses artist studios, apartments, offices, and restaurants. Flights to Durham touch down at Raleigh-Durham International Airport, less than 15 miles from downtown Durham.
