actually about 525; Imperial Grove is based on St. Louis, Missouri, which is about that distance away from Detroit, Michigan (the basis for Royal Woods)

On a side note, the city Ronnie Anne lives in is in between the other two cities, so it would take five hours for Lincoln and Clyde to get to her place and another five to reach Imperial Grove. so, Royal Woods and Imperial Grove are about ten hours apart.
