moose, I used to hunt for snakes for hours as a kid and have caught hundreds in my time but the biggest black snake I ever found was laying accross my parents driveway. I know the driveway alone was 7 feet wide and there was about a foot hanging off each side. It's a good guess to say he was between 8 and 9 feet long and as fat as my forearm. I also had a yellow rat as a pet that was just as big. Rat snakes are actually the best snakes to get as pets for a beginner.
