C152 PLT; OBTAINING A SVFR CLRNC OUT OF CTL ZONE AT MRI; TAKES OFF PERCEIVING GND CTL HAS ISSUED TKOF CLRNC.

Narrative

AT APPROX XA30 LCL TIME; I CALLED KENAI FLT SVC AND RECEIVED A WX BRIEFING FOR A ROUND ROBIN FLT FROM KENAI TO MERRILL FIELD. THE WX WAS FORECAST TO BE CLR. THE WX WAS CLR WHEN I DEPARTED ENA. WHEN I ARRIVED AT MRI; THERE WAS A FOG BANK MOVING IN. I REQUESTED CLRNC TO LEAVE AND WAS GIVEN A SQUAWK CODE AND TOLD TO TAXI TO RWY 33 AND FLY A R DOWNWIND DEP. UPON REACHING RWY 33; I STOPPED. AT THIS TIME; ANOTHER ACFT THAT WAS UNFAMILIAR WITH THE AREA; ARRIVED AND WAS ATTEMPTING TO LAND ON AN ACTIVE TXWY. THE TWR WAS BUSY WITH THIS PLANE AND THE FIELD WENT IFR. AT THIS TIME ANOTHER PLANE; C185; PULLED UP NEXT TO ME (C152). I WAS WAITING TO CONTACT TWR; AND THE OTHER PLANE DEPARTED. I CONTACTED TWR AND ATTEMPTED TO GET CLRNC. TWR TOLD ME TO CONTACT GND. I CONTACTED GND AND REQUESTED SVFR CLRNC. THE GND CTLR GAVE ME CLRNC OUT OF THE CLASS D AIRSPACE; CLRED ME FOR TKOF AND TOLD ME TO MONITOR TWR FREQ ON DEP. I REPEATED THE CLRNC BACK TO THE CTLR AND DEPARTED AT APPROX XY00. WHEN I RETURNED TO KENAI; I WAS DISCUSSING MY FLT WITH AN INSTRUCTOR; AND HE QUESTIONED WHETHER I HAD HEARD MY CLRNC CORRECTLY; STATING THAT IT WOULD BE UNLIKELY THAT GND WOULD ISSUE A TKOF CLRNC. I AM NOW CONCERNED THAT I MAY HAVE DEPARTED MRI WITHOUT PROPER CLRNC. IN RETROSPECT; I SHOULD HAVE SLOWED DOWN AND VERIFIED MY CLRNC WITH TWR.
