What's in the Big Box?

...that's what everyone has been asking when they come to our house lately.  Not only is there a huge box sitting in the middle of our great room (it's been there for a week now), but it sat on our porch for about 4 days first.  (It's heavy, I'm little.)  My boys are starting to accept it and treat it as a play table.

Check back next week for the answer.  Hint:  it's white.  (Okay, that's not a great hint but still it's a hint.)
