When I was growing up, my friend and I were riding our bikes down our street and when we reached his driveway there was a snake crossing the road that stretched halfway across. It must have been 7 or 8 feet and it was as big as my calf is now. Looking back, it must have been someone's pet boa or something and had gotten out of it's cage. We ran in to get his parents but when we came back we could not find it anywhere. It was hard to believe that a snake that big could just disappear.
