There used to be a place near Boone called Mondt's woods, but that fell through. The "tree huggers" won that battle when they found a couple of trees that "are not native to this area, and because of the highly erodable conditions, we do not reccomend this area be used for OHV recreation". They were the only vote out of seven "interested" groups" that said no to the project and that ended it. ONE VOTE. A shining example as to how little power we, as off road enthusiasts, have.
If there is something new in the works, I haven't heard of it. There is a place called Seven Oaks that is a ski/mountain bike/motocross area. Perhaps this is what you have heard about?
We are currnetly working on an area in Fort Dodge on the old bypsum mines. Other than that, I'm not sure of anything new.
