Dear Kevin, That's a very good question! Unfortunately, once you cross the event horizon into a black hole, there's no turning back. According to the equations of General Relativity, the singularity at the centre of the black hole lies in your future light cone, so there's no way to avoid it. Furthermore, the more energy you expend trying to escape, the more you 'feed' the black hole, and the harder it pulls! You would have to expend an infinite amount of energy to climb up your rope, and you would also need an infinitely strong rope, as the tidal forces would pull it (and you!) apart. This 'noodlizing' effect, whereby your feet experience a stronger gravitational force than your head, stretching you into something resembling spaghetti, is discussed further here by Dr. Craig Wheeler.
