In th fall of 2007 I went down to the local feed mill and bought a 50 lb bag of animal feed salt to salt deer hides to store them before processing for a jacket etc.

Most of the salt that has been used in my house since then for canning, shakers, etc. has come from that bag.

I have played with other salts such as the Himalayan and smoked salts. I have thought about trying to smoke some of my own. But I don't see huge differences and think that for most things salt is salt.
