If you are not a graph person (I'm not) do you have a spare bed? The top of a queen would be a good size for a play quilt. Do you have some scrap strips cut out, or a rope/string? Lay a strip down bending where you might want the road to go, and keep playing until you see something you like. Take a picture of it. Maybe change something, take another picture, etc. When you see what you like, tape newspaper together, draw on roads, mark "cities", cut out the shapes and sew, maybe one section at a time so you don't get lost, and just go for it. If you make a lot of turns in the road, your areas could be divided by the roads, and you can get a lot of areas in a quilt. You can applique the twisty roads on top of the area's edges so that you don't have to worry about sewing curves. Hope you can understand this, it's been a long day.
