I cut down a bunch of hard nuts that hang like grapes from a nearby tree and toss them ahead of me as I go. It’s good I do, too, because I have a feeling I’m missing the patches that indicate the force field more often than I’m spotting them. Whenever a nut hits the force field, there’s a puff of smoke before the nut lands, blackened and with a cracked shell, on the ground at my feet.
