Ok, so I know many of you don't find this to be as much of a turn on as me, but I will share anyway. Our land is on the site of aNative American settlement from years gone by. When we dug the footers for our garage, we uncovered the remains of a fire pit 18 inches below the surface. I have no idea what kind of estimate to make on the age of the fire, but I'm pretty sure it wasn't last year. I while later, I was kicking around the dirt and found an arrow head. I look forward to more discoveries in the future.
