I took this picture about 3 years ago. This post oak is the biggest tree I have ever cut. For comparison, the bar on the Stilh chain saw is 18 inches long. I don't remember the exact diameter but I think it was in the high 40's. I had only learned how to cut a tree larger than twice the bar lenght a few weeks earlier. This tree was 134 years old at least. The center decay prevented an exact age. In the course of cutting and splitting it, I found two bullets, two nails and two eyehooks. There were also two seperate colonies of carpenter ants.
