Milling Mockernut Hickory and Rocks?!? on Wood-Mizer LT40

While milling up more lumber to build the furniture for the co-working space going into Downtown Woodstock, Georgia, my saw blade ran into a first. I sawed into a rock that was inside of the bark about 14 inches into the log. I had to rip back the bark to get it out. I had never seen that before.
