Boas are common around here, it's a bit disconcerting to run into one in your yard or even in the house but it happens - luckily it hasn't happened to me yet. Over on the coast where we have a beach condo, friends have found some big enough to have eaten a cat or small dog. At that size, they need to go away. Mostly they just hire someone to catch them and take them farther back in the jungle. Here in the city, I don't think there are many around.
