Yes she is a pretty girl... Put her in a box and ship her to Edmonton if you really must let her go, I have a really nice male she would make a wonderful lady-friend for in a few years, just as long as my female doesn't get jealous, lol
My boas are very territorial, and won't think twice about striking at anything that moves inside their viv, but once you get the hang of it, you don't get too bothered anymore. Now a days, I use hooks to get them out, sometimes gloves if I want to shift things inside their viv in a hurry and don't want to risk getting bitten.
I think you should keep her, she's so beautiful, great pets, and they handle very well once out of the vivs.
