Smart as they generally are I reckon every so often one hatches that believes he is just too slick to get nailed. No surprise really, happens in DC all the time.I ran a crow over on my street going 25mph, he and a buddy were eating a pancaked squirrel. His buddy hopped over a couple feet but he had his back to me, I thought no way until I thumped over him and saw him in the rear view.
