I made the same mistake when I was a kid with a 3' 8" black rat snake. I was at camp when I caught him. I took him to the nature center, and when all the younger kids saw him they started to scream. He freaked out & bit down into my shoulder. We had to use a yard stick to pry his jaws open.

Morale of our stories - Leave wild snakes alone, even if they are good looking pets!
