There's a cartoon character who spends a lot of time tormenting Wile E. Coyote. Fortunately, ACME has given the coyote rather generous credit terms on anvils and balloons and explosives. The thing is, why doesn't the coyote simply order those boxes of gourmet food. In a few days he could be feasting on trout and pheasant--all sorts of things. But no, it's the bird that haunts his dreams he wants to kill.
And so, the chase goes on. The thing is, they're not very big. There was a Road Runner right out in my front yard yesterday.
