VEHICLE CROSSES IN FRONT OF ACFT READYING FOR TKOF.

Narrative

I HAD NEARLY COMPLETED MY TKOF CHKLIST IN THE RUN-UP AREA WHEN AN AUTOMOBILE DROVE OFF THE RWY; AROUND ME; AND STOPPED ON THE TXWY. THE DRIVER GOT OUT OF THE CAR AND BEGAN CHASING A DOG. I SHUT DOWN THE ENG; EXITED THE ACFT AND APCHED THE DRIVER AND ASKED HER WHAT SHE WAS DOING ON THE RWY/TXWY. SHE SAID SHE WAS TRYING TO CATCH HER DOG. DID SHE REALIZE THAT HAD SHE DRIVEN DOWN THE RWY ONLY A FEW MINS LATER THAT SHE PROBABLY WOULD HAVE COLLIDED WITH MY ACFT ATTEMPTING TO TKOF IN 1 1/4 MI VISIBILITY? NO; SHE DIDN'T. I MADE HER PROMISE TO WAIT EXACTLY WHERE SHE WAS UNTIL I TOOK OFF; AND THEN CAREFULLY DEPART THE ARPT; AND TO NEVER DRIVE ON THE ARPT GNDS AGAIN. SHE KEPT HER PROMISE; AND I COMPLETED MY CHKLIST/RUN-UP; AND -- CLRNC STILL VALID -- I TOOK OFF. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATES THAT WE SHOULD NOT WORRY ABOUT THIS SIT. IT WAS A FLUKE DEAL AND WILL NOT HAPPEN AGAIN. WHEN RPTR WENT TO CONSULT WITH ARPT MGR HE SAID HE KNEW ALL ABOUT IT. HOW? THERE ARE VERY FEW PLACES WHERE A CAR CAN ACTUALLY GET THROUGH FENCED AREA. DEER ARE MORE OF A PROB.
