Why not become a resort for short stays and a place for nudists traveling through?
For the same reason there are no other nudists venues in Montana, not a high enough volume of people to make it economy viable (too few people to pay to support the costs of having a staffed resort).
There was a nice little resort near Billings, too few people were paying to support its costs. So, they closed that's how that works.
Or you could start a place spend 250k to a million bucks, quit your job to staff it, Stand around there in hopes a few will stop by and give you 20 bucks, go for it!!!
We will post your link here.
