not so flat?

Forgive what may be a silly question and one that is strictly opinion and perception: but, if you live and Chicago and spend a lot of time downtown, does our continuously rising skyline and all that height spread out in the central part of the city actually make you feel, at times, that you are not in a flat city? Admittedly you can't drive up it, nor can you walk outside on it and see flowers and trees, but on some level does that skyline give you that sense of height that may just take the place of for the lack of hills? As in....driving inbound on the Kennedy from O'Hare, does that view in front of you suggest a flat city or one with its own man made hills (dare I say mountains)??????????????>
