Replying to Any local hills that are just a small park?

There are a few ski hills here in Massachusetts that are under 500 feet vertically, and have a run set up with a park. Just curious if there was anywhere that was just one run thats not indoors and is just a park! I could see it being a very lucrative idea if it was put in the right spot with the right setup/features. I know there would be a hundred hoops to jump through financially and with insurance and stuff, but it seems like a possible business idea. any comments or ideas about one of these popping up?
