You make a good point on this topic and have me thinking what would I do with the salt if everything around me was my land. I'd have to go with evaporating it and reclaiming the salt, I don't even think I would waste the
wood boiling it off but simply leave it in a
solar cooker.
I think just by asking the question you've solved it for allot of people, what would I do if there was no elsewhere for my problems to go. Reusing it for animal purpose is grand depending on what kind of salt you started with. I grew up thinking salt was salt and if you want to get fancy there's pink salt, my wife brought home a bag of grey pebbles and they mashed like icing in the mortar. That salt I drink with water and it helps me not get dry mouth from drinking too much water.
