THE PILOT & PAX HAD RETURNED TO THE HOME FIELD AFTER A LONG WORK DAY THAT BEGAN BEFORE 9 AM. UPON ARRIVAL AT THE AIRPORT FOG HAD COVERED THE NORTH THRESHOLD & THE AREA ADJACENT TO THE RWY FROM THE SW TO THE NE. ANOTHER ACFT WAS ALSO ARRIVING IN THE LANDING PATTERN. THE PILOT MADE 2 ABORTIVE ATTEMPTS TO LAND VISUALLY BECAUSE HE HAD POSITIONED THE ACFT TOO CLOSE TO THE RWY. THE LAST RADAR POSITION OF THE ACFT WAS A LEFT DOWNWIND LEG FOR RWY 17.
