I worked at one of those magazines for a while -- it's what took me to Greensboro, N.C. After I went back to freelancing, I bought a program called PC-USA, mostly so I could write a review of it. It consisted of maps of all 50 states, with facts about them.
Computers were so primitive then that the maps weren't much. In fact, I wrote a much better one myself -- as a type-in program for the PCjr. Remember that one? The book I wrote the program for was as dead as the PCjr before it even came out.
When I installed PC-USA on our computer at home, my kids gravitated to it, and that was a good sign. We left them alone with it.
After a while, though, my wife and I noticed something odd. The kids had been dinking around with it for half an hour and they still hadn't looked up North Carolina.
