Acorns....

We seriously have Acorns everywhere...for the last week and a 1/2 they have been falling on to the house making the most nerve racking sounds...then ROOOOOLLLLLIIIINNNNGGGGG down the angle of the roof and dropping on either the back cement pad with a ping or dropping in the front yard with a thud. When I walk outside...all I see is acorns. Why aren't the squirels taking them? They're everywhere!!
