Patrick Doherty, owner of Nuts & Bolts Brewing in Building 10 of the Pepperell Mill Campus in Biddeford, talks with a customer at the brewery on Feb. 23. Doherty, 27, a Biddeford native, tells milennials who come to his brewery that the city is not what it used to be. "I remember when I was growing up there was a 'for lease' sign in every store on Main Street," Doherty said. "Now it's difficult to find space." (Gregory Rec/Staff Photographer)
