It is so much fun to stumble upon a little animal out of the blue, like a tarantula ambling across a dried up Texas mud-flat.
Sometime they are are really laid back and will let you play with them. This one posed quite nicely as a used a wide angle lens to show more of the surrounding cracked mud to give a little sense of place. He was so laid back I eventually got him to walk over my hand.
