I drove across the Badlands today on SD Hwy 44.
Drove across KS on HWY 18 on the way to NE. KS is not the flat expanse people joke about. There are some serious hills in KS. I passed one spot on my way west that looked really wrinkled. That is the only way I can think of to describe it. It's as if someone took a part of the land and wadded it up like a piece of paper, put the dirt, rocks, and green stuff back on it. I thought of how awesome a place for kids to play.
