Peterson grew up in a railfan-friendly environment: his mother, Elaine, was George Krambles's sister, so she was well-used to the experience of standing on a crowded North Chicago Junction platform during the war, only to have a Central Electric Railfans' Association special stop and pick her and her fellow WAVES up. Once Art showed an enduring interest in railroads, his parents and uncle agreed to give him the education of a lifetime. Those experiences shaped Art's interests in the hobby and he shares them with succeeding generations—his kids have operated "L" and interurban cars (with instruction), while a pre-school grand-nephew is being taught to count the number of orange (or yellow) locomotives going by a railcam. Cursed by an interest in too many railroads, Art still avidly collects slides, and continues to shoot new slides every year. He's also interested in black & white images and maintains an extensive collection of these as part of the Krambles-Peterson Archive. Art has added entire collections to the Archive over the years, as well. His other rail interests include both public and employee timetables, Official Guides and Equipment Registers. Art, and his wife of 37 years, Tina, currently live in St. Charles, Illinois, 1 mile south of the bike/hiking trail that was the Chicago Great Western and about 3 miles north of the Union Pacific (ex-Chicago & North Western) Geneva Subdivision.
