OK, firing into the void, #retrocomputing question.
My family used a mapping program back in the 1990s (this was probably somewhere between 1995 and 1997), that was a shareware DOS program, either EGA or VGA, and the name started with "Interstate", and had a second word.
Additional info that might help, I know we got it from some shareware place somewhere in Ohio, that sold floppies of shareware at the Extravaganza show in Columbus.
Any ideas of what this was?
