The city where I attend school and the city where I live look like they're the same place... but they're actually two separate cities built practically on top of each other. There are, however, a few sure-fire ways I've noticed to actually tell them apart. The first is that in the city where I live, the buildings are much newer. Seeing as the city is newer, that does make sense. The city where I live is a bit higher, as well. Once you start heading down, you can tell you're heading to college town.
The easiest way is road design.
Seriously, I don't know who designed the roads in my college city, but it's RIDICULOUS! Which is actually a shame, because most of it is really nice. But honestly! Everything is so tight, and you can't see any signs because there are trees and other obstructions everywhere, and suddenly you're supposed to be going a lot faster in areas that are a lot narrower and... and...
I think I'm getting another bus pass this year. :P
Fare thee well, friend!
