Dad loves hunting for arrowheads. He's been walking freshly plowed ground since he was fourteen. He headed out today, since its been raining and that is usually a good time to find them. Success! He found his first arrowheads of the year in the fields behind our house.
It is amazing how these have been in the ground for hundreds, perhaps thousands, of years and he finds them with very little effort. I never can find any the handful of times I've gone with him. But then again, I don't care like he does.
