He's a bigun.

Some photos from this past week...
Below is a large crazy looking lizard that I looked up as being the male Common Chuckwalla (Sauromalus ater). I saw this guy (and two others) on my hike up Camelback Mountain in Phoenix last Saturday. He was pretty large, with around an 8 inch body and a 12 inch tail. More info on the species here.

I snapped this picture on my ride through South Mountain last night. I have come to realize that I love riding at dusk, once the sun is below the rim of the western mountains. The light is the best then and I totally forget about the heat. I also love the solitude of riding alone, no music just the soundtrack of life to help me release the stresses of the day.
