Lanford is a fictional town, but Fulton County, where the Conners live, is real. Darlene and Molly are allowed to attend a concert in Rockford, which is supposed to be a two-hour drive one way, depending on the exact location. Rockford is actually approximately 3 hours. They attended without an adult. But Darlene and Becky weren't allowed to attend an out-of-town concert without adult supervision. The writers were all over the map with city locations and travel durations.
