It took me longer to get this one done, having concepted a lot more with how I wanted it to look, but I present to you all the GTA State of Michigan.
As you can see, I've gone for a more GTA V-styled map for this one, and it is not exactly to scale. Some roads within the towns are not included, or towns appear larger than they would just to make them more visible on the map. I also think I might have made the large city look larger than it should by packing more roads into small areas. That large area is a recreation of the Grand Rapids, with a bit of Ludington mixed in to the north-west of it. The Upper Peninsula's largest city is a recreation of Menominee.
Other areas of the Lower Peninsula include a town based on Traverse City, a town just off the tip of the Grand Rapids that doesn't have a base location but could be likened to Rockford or Cedar Springs, and right at the top a recreation of Mackinaw City. The Upper Peninsula is split into three sections, with the west having the large resort and a truncation of Copper Harbour, central having the city of Menominee, Marquette, and the town of Grand Marais, and the east having St. Ignace, Sault Ste. Marie, and truncations of De Tour Village and Manistique.
There's a massive amount of sea within the south-western part of the map, but only one small island filling out the area. There's opportunity to put more islands around that area, but I decided against it for now as they'd be smaller and not much detail would be able to be placed on them if any. I'd have four to the south, one to the north-east, and one to the west of the featured island.
