How high can you go?

This is my life...My house is really a gym. Our toy box is filled with basketballs, footballs and baseballs and I'm not talking about the Nerf brand. I took shot after shot of this yesterday and I still don't think I got what the hubster was looking for. That's the oldest, Big Mac, obviously working on his vertical. I think he's at 17 1/2 inches, but i will have to confirm that. Not bad for a 3rd grader. :)
