Salt and the Winchesters

Do you know CW's Supernatural?

I realized yesterday that salt to avoid demons/evil is actually real story. Spiritual world in Indonesia is high rated. But the mystique behind our asian trait, is not well aware to commoners.

Not until yesterday that I find the winchesters' boys can be right on course.
(Or the writers to that fact)

I wonder if silver bullets also true? Hm. :D
