This tree is located just outside an army base. If you look closely at the top you can see a line where it seems 2 sections of the "tree" have been put together.
Walking around Seoul taking photographs means spending a fair amount of time alone. Doing what I love, I enjoy this time. On my walks throughout the city I've come across others that are alone, partaking in their hobbies and interests (although I don't really know what the guys in their cars were up to).
