Does anybody know what the world record RTB is? Or if not, what is the largest you've heard of personally? I'm mainly wanting to hear length. Reason be is there was an ad in our local paper saying they had a 12 foot RTB and were asking $1,500. I've never studied boas like I have other species, but I've only heard of them topping out at around 9foot, maybe close to 10, but definately not 12. Anyway, if anybody could help, I'd appreciate it.
