Suppose you’re hunting voles. I know, it’s not on any list of grocery items, but just suppose. It’s winter. It’s 20 Below. And you’re hungry. There are a lot of holes. Which one are you going to hunker down by or try to dig up? This one?

Which one? The one on the left below? The one on the right?

Yes, the right.

Voles don’t hold their breath.
