Hello from Southern Arizona,
Where we continuing the "creepy" festivities with the celebration of Dia De Los Muertos. As part of the celebration I thought I would stay away from the classic witch head, broom, and ghost images and post what I think looks like a skull (a symbol of this tradition). Again, this is another of my "return to DSLR" images.
