Windshield smashed

At about 2030 (8:30pm for you day weenies), one of the local cockroaches in Dallas found the goodness in his heart to heft a large rock or brick at my windshield.  Luckily, it did not penetrate the safety glass, but I did get sprayed with sand-sized glass pieces.  This happened at about mile marker 478 (just east of Exit 477) on I-20, the LBJ Freeway on the southeast side of Dallas.  All I saw was the object coming up from the grass out of the dark and BAM! I was covered in glass powder!  If the @$$h01E who threw it were a bit stronger, or the object a bit larger, or I were to have been driving faster than the 60mph speed limit, my head would have been splattered across the back of the driver's seat.  Luckily, Lori had gone back to the sleeper about a half hour before this.  I'll try to get a picture.
