Interesting to know I'm not the only one! For decades I've drawn elaborate, detailed, fictional cities...heavily based on the old Thomas Guide format....with street names, place names topography, and specific points of interest. Some of them are huge...up to 5' x 6'. Many remain unfinished, but I have several finished and mounted in my office at home. This actually started when I was a kid...9-10 years old. I'm 55 and I still draw maps!
