Narrative

LANDED AT LAKE NORMAN ARPT. TAXIED TO APPARENT OFFICE AREA AND SHUT DOWN ENG. WIFE (PAX) AND I EXITED THE PLANE. NO ONE AROUND. CALLED DAUGHTER IN NEARBY TOWN TO PICK US UP. LOOKED FOR A TIE-DOWN. FOUND A SPOT WITH APPROPRIATE 3 ROPES IN NEARBY FIELD AREA. RESTARTED ENG - - WIFE NOT IN PLANE -- AND PROCEEDED TO TAXI ALONG A NARROW ROADWAY TO TIE-DOWN. SMALL VOLKSWAGEN ON L AND CESSNA 120 ON R AT TURN IN ROAD HAD ME CAUTIOUSLY GO THROUGH. MY CONCERN FOR TAIL CLRING VOLKSWAGEN AS I TURNED R TO FOLLOW ROAD; LED ME INTO SOFTER GND ON L. A CHEROKEE ON R OF INTENDED TIE-DOWN; AND MY MISJUDGING DISTANCE FROM ROAD EDGE TO POLE; GOT ME TOO FAR L. WHEN L WING HIT POLE I THOUGHT I WAS INTO POTHOLE AND GAVE QUICK PWR BOOST -- IMMEDIATE 90 DEG L TURN AS PLANE PIVOTED AT POLE CONTACT. I SHUT DOWN ENG IMMEDIATELY. MY PROB CAME WITH BEING ON A STRANGE FIELD AND MISJUDGING DISTANCES BTWN POLE; ROAD EDGE AND CHEROKEE; THEN THINKING I HAD DROPPED INTO A POTHOLE. MAYBE PLTS FAMILIAR WITH THE FIELD WOULD HAVE TAKEN A DIFFERENT PATH; RETURN TO RWY; BACK-TAXI AND UP HILL TO ANOTHER SECTION OF THE FIELD.
