Hey Aaron, good to hear from you. I actually checked some of my BP books and noticed that the tail below the vent (under belly side) was not as bright on the snakes in the book either, and I think its maybe just a characteristic of the snake.
She's really growing. We measured her today and she was 30.5". Just a few weeks ago she was 29".
It's good to be back online for a change... I've been working/traveling for work like crazy lately.
