74, this concept is definitely worth looking into more. I’ll see my son the weekend after this and will talk to him about it. As for critters, I have deer coming into the yard in abundance, bears, turkeys, a bobcat, and most likely coyotes & fox that I haven’t seen but which neighbors say have taken their chickens (& with piles of feathers left on my lawn), plus whatever moves only at night that I never see.
