It's a nice idea, but it doesn't actually count as a road access for adjacent homes, which means they take up more space than plopping a bus access. Is there no way to fix that?
I ctrl+alt+shft+R, click the map name and viola!
Nothing.
I see that you've got the file here but there must be something about the size or format that needs to be tweaked and you should let people know. =p
Also, for the most part, the cliffs are that steep around the river, but some places (like the plains near downtown), it looks like it's just an effect of the way the program kinda screws up around litorals: check out https://www.simtropolis.com/content.cfm?mode=omnibus&view=56 if you haven't.
Thanks! this's inspired me to create some maps of my stretch of the Ohio. The only complaint I have is the way the city regions are set up on my map but it looks different from the one thumbnailed here. I prolly just ended up w/ the wrong one in my folder.
