Mapguy here.
I just wanted to say that I fucked up last night with the route 4 map file I posted.
Here's a corrected version. You don't have to stay within the grassy area, exactly, that just shows where exactly the route 4 grid spaces are on the map. In fact, you'll want to add beyond the grass near the bottom for the start of the route, since the exit from the forest (which is now already on the map file), is near the bottom
Here's the file:
