I used to make maps. I made a lot of them, actually. It was during a time that I had an enormous amount of time to dedicate to being behind the keyboard and doing the research involved to find sources for 2nd, 3rd, and even 4th or 5th-level administrative subdivisions.
Sadly, my time is more precious now and I no longer attempt to the mapping. If you find a map that is incorrect, feel free to use it to update and replace with a more current or corrected version.
Enjoy your hobbies and live life. It is a short journey we partake.
