Thanks for the compliments, everyone. The tree trunk is about 8-10 feet in diameter. I found it while driving from San Antonio to Corpus Christi, Texas. There was this abandoned RV park I stopped to shoot, and the property owner stopped by and gave me permission to shoot not only in the RV park (I had been shooting from the road), but a family cemetery behind the park with graves dating back to 1799, and also his front yard and this tree. That spur-of-the-moment stop ended up being the best shooting of the whole trip.
