Well it is not luck, you probably got a snake that was well adjusted and came from someplace that took good care of there snakes. All but one of my bp came from a local breeder i found in my area, they are all the same as yours. So it is my belief that how they were kept before we get them makes a big difference. On a side note the one that i did order from a well known breeder, nasty lil sucker!! I am sure i will get him to calm down before he gets to big, but nothing like my well cared for local babies! Congrats on the awesome snake!
