Lol I am going to copy and paste a reply from a similar thread I replied to....

Personally right behind my SD REtics my boas are my favorite snakes..... I love their personalities..... I do have several other pets (birds, cats, dogs, ect and 3 kids) I dont really ever worry about my boas getting out (but all are housed in racks or 4ft locking cages). I do love my boas, but one thing to keep in mind is size.... I know it doesnt happen often but recently a good friend of mine (I have snows and motley het snows from him, and he has some of my blood boas ect) picked up a 6 year old snow female that is pure columbian and pushing 11ft and 60lbs.... so on the rare occasion even Colombians can get big.... But from my experience and the 20+ boas I have they vary rarely have bad attitudes and are usually a joy to be around.....

Another great thing about boas, is so many of the morphs have come down in price where you can buy something cool at a more affordable price....jungles, motley, albino, sunglow, albino motley, all morphs that can be had for less than 500 bucks....
