I have a friend that works for a Semi shipping company. They haul multiple semi trucks hooked up to each other across the country. Any way when they unload they have all this rough cut lumber that come off the rigs and he gives it to me for free. He said it’s oak. Some obviously look like oak but some I don’t recognize. From what I found online they look like pin oak or live oak. What are your thoughts? Two different pieces below both planed and ripped.
