As for salt, you know what The Humungus would say...
"There has been too much violence. Too much pain. But I have an honorable compromise. Just walk away. Give me your pump, the oil, the salt and the whole compound, and I'll spare your lives. Just walk away and we'll give you a safe passageway in the wastelands. Just walk away and there will be an end to the horror."
