Colombian. Just a good all-around snake that gets big but not huge and has a great temperment (for a reptile with over 200 razors in it's head, I mean). I made the mistake of having my very first snake way back in the 80's be a Burmese.

Yeah, BCI's tend to be a little more forgiving when it comes to husbandry (the snake kind, not the "That's-the-third-time-you've-come-through-that-door-at-two-in-the-morning-this-week!" type of husbandry).
