These images are of a bouldering structure that was fabricated to resemble a twisted tree trunk.  Honestly, this thing is the most fun you can have with both hands and feet at the same time. The texture is like rock, perhaps a bit more slippery, but manageable.  There are cracks and hand-holds formed as part of the surface, so nothing can fall off or be stolen.

I discovered this amazing structure while training for a 5K; it’s right at the end of the course, so I was too exhausted to jump on and pull down (good excuse!).  But I am never too tired to whip out the iPhone and get down to the business of photography!
