They should have higher wall like fences , liek steven said before - this would complete it.
I've tried this in another way ,watch this pic :
Rock walls with elevathed path. It also works.This roof has a foodcourt on it. I do let some of the poles of the path standing,so that is more realistic.
I believe this way you can make real stables in stead of the shelters,it's jsut cool.
thank you steven. I'm sorry if this post is wrong.
but it would be coolest if you could actually built real buildings in stead of this surrogates
