So I was letting my dog out for the night, and I saw the biggest one I've ever seen!! Didn't have my phone or is have a pic, but the body was 7" long with 3 inch tail, the head was about 3/4 inch across, I've seen him twice but this was the first that he was along my brick wall for a good measurement, largest yet and I don't think I'll see bigger, just had to share!
