"Does Nashua have anything to offer besides malls?" asked a skeptical friend when I mentioned I'd be visiting New Hampshire's second-largest city. The answer to that question is a resounding " yes, " although anyone who's seen Nashua only from a car window on Route 3 might think otherwise. So let it be known: Nashua has both a historic past and thoroughly modern present, including high-end dining, luxury riverside condos carved out of former mills, a walkable downtown with boutique shops, and a cultural life that ranges from jazz to symphony. There's also precious green space amid the urban landscape: Mine Falls Park, a 325-acre network of forest, fields, and wetlands, offers city dwellers a chance to boat, fish, hike, and cross-country ski without leaving town. And during baseball season, the Nashua Pride play at Holman Stadium, a diminutive ballpark with minor-league charm and major-league amenities.
