Ya, I have heard Elm Creek is the shit. As far as there being other things. I already know this. I am getting prices of insurance and trying to find land that would actually work. The national forrest already said no to one spot. Its a long battle but if it would open it would be all worth it.
The project underway here in Michigan worked with the city of Lansing parks & rec, leveraging an existing city park. They are turning it in to a sledding hill and also the terrain park. Might be something else to consider.
