I happen to pick this up at an antique store.
As a certified school librarian, I like presenting information to others.
Sometime around 2010 we were in TN on vacation at
Pigeon Forge (great place) and took the long ride to
this location.  No much there to see anymore but the sphere.
There used to be a restaurant in the sphere, it was closed.
Not many attractions in the area for vacationers.
Check any of the "vacation" apps for what is around.
