"Downtown Lowell is now widely considered a tourist destination for history buffs, and over the last decade, many historic buildings have been restored. The Boott Cotton Mill complex is home to luxury apartments, office space and lofts. Trendy stores and coffee shops have opened downtown, and the area has become a hub for great restaurants, fun nightlife, and Lowell’s annual events."
I'd be happy with only half of these problems. Maybe someday, someone, will figure out a way to turn it around into something better.
