when I was a little kid, our back yard bordered on an undeveloped field, and the back fence was covered with ivy so deep I could thrust my arm into it an not reach the fence... when it was like that, you could find these little critters all over the place, sometimes they got stuck in the house with no food or water, and after a few months when you moved a piece of furniture, you would find a sekleton... and since it's texas, and the ground around your house gets wet/dry/wet/dry and the foundation is constantly shifting, (at least on that old house) sometimes they would get caught in door jams and crushed as teh house moved. very sad.
They are actually very very cool lizards. The male has a gorgeous red puffer on his throat to attract a mate, I used to watch these little critters for ho urs at a time.
Oh, and you haven't seen a true texas lizard until you have seen a full grown horned lizard... it's a rarity now days, infact, I have only seen them a couple times in my life... but wow. Looks like a 1/2 foot long ankleosaurus.
