i think it would be popular and possibly successful. if you could find a rope tow for cheap and have some cheap concessions, you could have cheap passes and probably get a lot of people to come. get old rails from the local mountains. i found a decent slope on a lot outside of burlington thats for sale, and we thought about it, but it would be difficult to get going while in school. but i say if you go for it, you could most definitely find some help and funding from people. insurance would be very difficult though.
BTW, i have an old 14 foot or so flat bar that im planning on bringing up to burlington and setting up in the woods somewhere for people to use whenever. if people have other rails and a good suggestion of an area to put it in that would be sweet too
