So just so we're all clear, this is what happens when we are derelict in our backyard duties and do not empty or cover the (very full) sandbox at the end of the summer.
Mix together some rain, a little snow, some random toys, below freezing weather and of course, the 20 pounds of sand that live in the sanbox and there you go, a frozen sandbox.
Gross. And tons of fun to clean come spring :)
Are you a Mom?
Of course you are,
your shirt is dirty :)
