Marbles, marbles, everywhere!!

David loves marbles. Probably about a year ago, he got the game Kerplunk. Once John and I figured out how big of a pain that game is to play and wouldn't play it anymore, David just started playing with the marbles. He'd make tunnels, goals, obstacle courses, you name it. So, for Christmas, John found a huge marble structure for David. I'm not sure he realized what it was when he opened it on Christmas morning, but he soon learned! John took these pictures of him getting it all set up...you can see it's quite complicated!
