The Nemaha Ridge runs from Kansas to the Arbuckles, basically along I-35, so you're living on a fault line. How do I know this? I'm taking an "O.L.L.I." adult education class (thru OSU) - Understanding Hydraulic Fracturing. It's informative without being propaganda for either side of the argument. This course was previously taught in Stilly. Not here to pimp OLLI, but the membership/courses are worth checking into.
