Factual error: During the stop in the small town while still in Texas, and Tallahassee breaks all the windows in the minivan, a Bank of Coweta sign is visible over one of the buildings. The Bank of Coweta is a local bank in Georgia, and has no branches outside of the state.
Factual error: When Tallahassee and Columbus open the crashed Hostess truck, a huge pile of individual Sno-Balls packages pour out. A real delivery truck would have the product packaged in boxes on shelves in the back of the truck. Even if a Hostess employee was frantically filling the truck before he fled for some reason, Hostess products come from the factory and distributor in boxes.
Factual error: During action sequences in the amusement park the girls attempt to escape in their Hummer, and a zombie head-butts the passenger window, causing it to shatter. As has been demonstrated on numerous occasions, including a Mythbusters program, tempered automotive glass will not break when struck by a blunt object and that would include a zombie's head. Only a blow from a sharply pointed object will break tempered glass.
Answer: The names come from their hometowns, not their destinations. Witchita is much older than Little Rock; she could have spent the majority of her childhood in Witchita before her family moved to Little Rock where her sister was born. She still considers Witchita to be her "hometown".
