I think the monorail is inevitable

They could superimpose an image of some mountains with an image of the monorail to the "raw" green edges of our Springfield, similar to the faux mountains at the top of our springfield, and/or the trees on the sides of krustyland. and only have small section(s) of the monorail track and wreckage for us to place inside our actual town. . As we buy new land the faux image would just scooch overto make room. If they add new land, a similar system. Get rid of that plain ugly dark green on the two unfinished sides of our town.

Would changing the dark green to a pictorial use up a huge amount o?f server space?
