Other than the landfill ?!? Or maybe a freeway overpass :-)
Actually, the Fall Creek and White River valleys offer some short but significant hills suitable for a good hill workout. And there are definitely some notable hills on the Eagle Creek, Southwestway, and Belzer maps.
+ holliday pk and parking garages :)
Not exactly Yellowwood, but it will have to do... ;-)
Our house is in the white river valley, and I ran up and down the hill out of the valley.
