A PA28 SINGLE PLT DEPARTED FROM 4J6 ON RWY 22; BUT ANNOUNCED HE WAS DEPARTING RWY 31.

Narrative

I FLEW FROM LOU TO 4J6 AND LANDED ON RWY 13. I ASKED FOR FUEL AND WAS DIRECTED TO TURN OFF L ON A TXWY. I WAS FUELED AND TOLD TO TIE DOWN AT THE END. ON RETURNING TO DEPART; I RECALLED THE LNDG; BUT FAILED TO RECALL THE LAYOUT OF THE ARPT. I CHKED THE WIND AND IT WAS CALM. I DID MY NORMAL PREFLT; RUN-UP; AND TAXIED ONTO THE TXWY; WHICH EXTENDED ACROSS THE RWY BY OVER 1000 FT; AND THOUGHT IT WAS THE SAME RWY I HAD LANDED ON AS THE INTXN WAS DISTANT. I RPTED I WAS TAKING OFF ON RWY 31 AND TOOK OFF. IT WAS NOT UNTIL I HEARD MYSELF BEING CURSED BY A VERY NEARBY XMITTER (ANOTHER NON-MOVING ACFT) THAT I REALIZED MY ERROR. I ISSUED APOLOGY; CONTACTED JAX APCH AND DEPARTED. THE CURSING AND NAME CALLING MAY HAVE BEEN ILLEGAL; BUT IT WAS DESERVED. I CANNOT BELIEVE THAT I MADE SUCH A GRIEVOUS ERROR; EXCEPT THAT I HAVE USED MANY SMALL ARPTS WITH RWYS VERY SIMILAR IN LAYOUT AND APPEARANCE TO THIS ONE. HAD I CHKED MY COMPASS I WOULD HAVE REALIZED THAT MY HEADING WAS ABOUT 220 DEGS AND NOT 310 DEGS OR HAD THERE BEEN OTHER TFC ON THE RADIO I WOULD HAVE HAD MORE NOTICE OF MY ERROR.
