This morning we woke up to white paint all over our back porch.  Our porch is elevated about 20 feet in the air with no access to it from the outside (ie, no stairs).  It appears as though the person/people tried to throw the paint can once, missed, the can hit the wall and some paint came out, then it hit the driveway where there is a paint can ring.  They tried a second time and made it up to the porch where it “exploded” on our porch and windows.  Has this happened to others?  Some of my friends said it could be a high school prank?  Any advice out there?
