No, It's Not a Bomb!

While it may appear in the picture below that our backyard was hit by a small missile, this indeed is not the case.  Upon further inspection note an abundance of wood on the ground, an orange tape measure, and some nails on the table.  I think I even see the bottom of a structure in the top middle of the photo!  What could this be?  Can't bare the thought of continuing your day without knowing?  Sorry, you're out of luck!  Check back in a few days for the big reveal! -Carrie
