Narrative:

While on a VFR trip from salisbury, md, to york, PA, I mistook a VFR landmark and inadvertently entered the bwi arsa. I was called out of bed to go on this trip (with 20 mins from phone call to airport arrival). The plane was ready and I jumped in and estimated my course en route. I flew north on a course of 355 degrees at 2000' MSL to avoid strong northeast winds at altitude. I reached what I believed was the elk neck peninsula in the northern chesapeake bay (a point at which R4001A is cleared and a turn to a westerly direction is permissible). I turned to a heading of 300 degrees to navigation toward york. I must have misjudged my landmarks and the winds in part due to haze, fatigue and ill preparation. I therefore turned too soon and penetrated the bwi arsa and possible R4001B before I realized my mistake. I was not in radio contact with bwi since I anticipated being well to the northeast of the arsa. I reoriented myself to the westminster VOR and continued northward from the VOR. The flight was safely and uneventfully terminated at york airport.

Narrative: WHILE ON A VFR TRIP FROM SALISBURY, MD, TO YORK, PA, I MISTOOK A VFR LANDMARK AND INADVERTENTLY ENTERED THE BWI ARSA. I WAS CALLED OUT OF BED TO GO ON THIS TRIP (WITH 20 MINS FROM PHONE CALL TO ARPT ARR). THE PLANE WAS READY AND I JUMPED IN AND ESTIMATED MY COURSE ENRTE. I FLEW N ON A COURSE OF 355 DEGS AT 2000' MSL TO AVOID STRONG NE WINDS AT ALT. I REACHED WHAT I BELIEVED WAS THE ELK NECK PENINSULA IN THE NORTHERN CHESAPEAKE BAY (A POINT AT WHICH R4001A IS CLRED AND A TURN TO A WESTERLY DIRECTION IS PERMISSIBLE). I TURNED TO A HDG OF 300 DEGS TO NAV TOWARD YORK. I MUST HAVE MISJUDGED MY LANDMARKS AND THE WINDS IN PART DUE TO HAZE, FATIGUE AND ILL PREPARATION. I THEREFORE TURNED TOO SOON AND PENETRATED THE BWI ARSA AND POSSIBLE R4001B BEFORE I REALIZED MY MISTAKE. I WAS NOT IN RADIO CONTACT WITH BWI SINCE I ANTICIPATED BEING WELL TO THE NE OF THE ARSA. I REORIENTED MYSELF TO THE WESTMINSTER VOR AND CONTINUED NORTHWARD FROM THE VOR. THE FLT WAS SAFELY AND UNEVENTFULLY TERMINATED AT YORK ARPT.
