The Sabin Plateau in NE Portland is pretty amazing in terms of how level it is. Coming from Seattle I am used to dealing with hills in every direction. In this section of Portland there is just this large expanse of level land whose streets are pretty much laid out in a grid. It makes for a wonderful walking experience. In the distance you can see a minivan moving from right to left. After 5 years of walking this neighborhood I am still intrigued by the architecture and design styles I run across.
