Among my mental gaps are some ludicrous misunderstandings about salt. Generally, I’ve been “buffaloed” about its origin, as well as the subtlety of Morton Salt’s 100-year-old ad. Still, I’ve “soldiered on.” During elementary school,
our teacher asked if I knew where salt comes from. “We get ours at Safeway,” I answered. (I think it was the same grade when I admitted thinking that chocolate milk came from brown cows.)
