Ha! It's not fun, but don't pay attention to me. I've been having back trouble recently and the thought of lying on the table for any length or even getting tattooed on my back is a really unpleasant prospect at the moment. I'll get back to it when my other back problems settle down. In the meantime - I work on legs.
That said, I think backs often break people. There are a lot of people out there with unfinished back pieces. I wont be one of them, though I am taking my time.
