Last weekend, we went to visit my sister in Columbia, MO. She was in visiting from Washington state. While we were there, we checked out The Big Tree a 350-year-old burr oak that is the largest burr oak in the country and the biggest tree in the state of Missouri. It sits along the Katy Trail in McBaine County, MO.
This guy buzzed overhead a few times while we were there.
