Tom Swift Jr. created his inventions on the grounds of Swift Enterprises, though there was a Swift Construction Company not too far away. Swift Enterprises was supposed to be four miles square. When I was a kid, I spent a great deal of time wondering if that was four square miles (two miles by two miles) or four miles by four miles (sixteen square miles).
One of the other things I was fascinated by when I was a kid was Disneyworld. I had been to Disneyland, but the idea that Walt had this huge expanse that not only included a Magic Kingdom, but also campgrounds and lakes and other parks really touched my imagination.
For Maxxim Industries therefore, I created a huge expanse of 180,000 acres, dotted here and there with industrial parks and business campuses, as well as power plants, its own airfield, and even a spaceport. Of course it also had rivers and a lake, a cactus park, convential parks, and for some strange reason, the high school from the adjascent Maxxim City was also on the Maxxim Industries grounds. This allowed the students to take a monorail train to school every morning.
I made a great map, but lost it in the move to my den this past summer. As soon as I find it, I’ll post it here.
