M20 PLT LANDS AT WRONG ARPT FOLLOWING A FRUSTRATING IFR FLIGHT.

Narrative

IN SUMMARY; INCIDENT WAS JUST LNDG AT THE WRONG ARPT. I WAS FLYING THE THIRD LEG OF 3 AND IT WAS THE END OF A LONG DAY OF FLYING. THE THIRD LEG WAS FLOWN ON AN IFR FLT PLAN TO HWV. THE WX AT DEST WAS FORECAST TO CLR BUT WAS MVFR; OCCASIONAL IFR AT THE TIME OF MY DEP. I ELECTED TO FLY THIS LEG UTILIZING MY IFR FILED FLT PLAN. THE CLRNC I RECEIVED WAS NOT EVEN SIMILAR TO THE FILED FLT PLAN. PRIOR TO DEP; I WAS UNABLE TO RAISE CTR TO OBTAIN MY CLRNC ON EITHER THE FREQ THEY GAVE ME; OR THE TELEPHONE NUMBER THEY GAVE AS AN ALTERNATE METHOD. SINCE DEP WAS VFR CONDITIONS; I ELECTED TO PICK UP THE CLRNC AFTER TKOF. I HAD ALREADY ENTERED THE REQUESTED FLT PLAN INTO MY GPS IN THE HOPES THAT IT WOULD BE AT LEAST CLOSE TO THE CLRNC I WOULD RECEIVE. IT TURNED OUT THAT THEY WERE NOT EVEN CLOSE. FURTHER; THE CLRNC WAS CHANGED ENRTE AT LEAST 6 TIMES; PLUS VECTORED CHANGES AND ALT CHANGES ISSUED BY ATC. THE FINAL SEGMENT OF THE FLT WAS THROUGH THE JFK CLASS B AIRSPACE; INTO ISP'S CLASS C. I WAS BEING GIVEN VECTORS RATHER THAN FOLLOWING A RTE. WHEN CLOSE TO DEST I HAD THE ARPT IN SIGHT AND CANCELED MY IFR CLRNC ABOUT 10 MI FROM DEST. I MADE ALL THE PATTERN CALLS FOR ENTRY; TURNS AND LNDGS AT HWV; BUT IT TURNS OUT I LANDED AT AN ARPT 6 MI AWAY WITH THE SAME HDG RWY (RWY 33). AFTER TOUCHDOWN THE ENVIRONMENT DIDN'T LOOK FAMILIAR AND I NOTED A TWR. I TRIED THE USUAL GND FREQS IN CASE THE TWR WAS OPEN; WITH NO LUCK. THERE WERE PARKED ACFT; BUT NO ACFT IN THE PATTERN. SEEMS I LANDED AT 3C8 INSTEAD OF HWV. WITH A VISUAL CHK FOR TFC; I DEPARTED AND LANDED WITHOUT INCIDENT AT MY INTENDED DEST.
