A future bedroom or where I send bad kids???

Devin opened up the "hole" that leads to the unfinished section above the garage so that we could paint.  The kids were so amazed of what was behind the wall and that we will eventually finish it.  I know this is bad but I couldn't resist telling them that if they got too bad I would have to open it back up and put them in there.  They looked at me like you wouldn't really do that would you??  I had never looked inside it either and was amazed a what a large space it is.  I am hoping that we can not only finish a bedroom and bath in there but also some extra storage space.  We will see.  I was ready to call a contractor right then but I guess it will have to wait.
