They dig in with tiny back feet, dart across the path of oncoming trucks who's wheels, miraculously miss the little creatures by millimeter. Don't slow down, don't flinch, don't miss a beat, they are at full throttle. You catch a movement in the corner of your eye, and before you can react with more than a curse word, THUMP and BUMP, their dead.
Where I'm from, they have laws. You can not molest a black squirrel. Squirrel molesters may, however, have a field day with the brown ones. I was fortunate the one who killed himself using my car as a weapon was a brown squirrel (wipes sweat beads from forehead).
Be warned, participating is this ritual, even unwittingly, will ruin your day.
BEWARE THE KAMIKAZE RABBITS.
