Yeah, I need to get around to getting one of those stumps. From everyone I've heard who has one, it's usually their snakes favorite hide.
Back on topic, welcome aboard! And thanks for the pics. Pics are grrrrrrrreat! Also, I really like your setup. The way you twisted the vine up and set it on the stump looks really good. I know it's simple and I think that's why I really like it. I do agree with others that you might want to consider some more cover though. Especially while she's young. Cover enhances security a little bit, effectively reducing stress and encouraging exploration and activity. It also provides obstacles to climb over and onto, which encourages exploration and activity while also effectively providing more "floor space" and leading to more exercise.
