With big-box stores, megamalls, and online sellers dominating the retail landscape, the pleasure of shopping at mom-and-pop stores in a quaint, small-town Main Street shopping district is getting harder to find. But every state has a few such homespun settings left. Here are some of the best downtown shopping districts in the country — each in a town with fewer than 90,000 residents. (More than half are home to fewer than 10,000 people, and some claim populations in the triple digits.) And if you’re intrigued by overlooked spots, the Most Underrated Town in Every State would be worth a glance, too.
