All it took was a trip to New York City two years ago. Virginia and Mike Nowak, both 45, had not been in the toy business since 2009 when they closed their Great American Toy Co. store at 3333 S. Coulter St. after 17 years. But on a spring break trip in 2014, they found themselves browsing through a small toy store in Grand Central Station. Virginia said when she met up with her husband several minutes later, they both had that same familiar feeling. “Mike said to me, ‘You want to do this again?’” she recalled.
