A frog starts at the point $(2, 3)$ in a 7x7 square grid defined by the vertices $(0, 0), (0, 7), (7, 7),$ and $(7, 0)$. Each jump is parallel to one of the coordinate axes and has a length of 2 units, and the direction of each jump (up, down, right, or left) is chosen independently at random. Calculate the probability that the sequence of jumps ends on a vertical side of the square.
