I saw one of those Iguana creatures in my backyard this summer. Thought I was seeing things. At first I thought it was a squirrel making it's way through the crepe myrtle trees . By the time I figured out what I was looking at and had made my way to an Airgun and back to the yard it was gone. It was about 2 1/2 long. It must have been either turned loose or had escaped. No one believed me until an article in the local newspaper regarding these lizards being found in the area.
It will mostly freeze this winter in this region.
