On December 24, 1998, about 1445 eastern standard time, a Cessna 150, N252WM, registered to a private owner aborted a takeoff at a private airstrip in the vicinity of Pembroke Pines, Florida, and collided with a fence and guardrail. Visual meteorological conditions prevailed and no flight plan was filed. The airplane sustained substantial damage. The private pilot and one passenger reported no injuries. The flight originated from a private airstrip (Macivor Field) about 1 minute before the accident. The pilot stated he started his takeoff to the west. After rotation he was not comfortable with his altitude in relation to obstacles off the departure end of the runway (trees). He aborted his takeoff late. The airplane touched down on the runway, continued off the end of the runway and collided with a fence and a guardrail. When asked what caused the accident the pilot stated, "poor judgement to abort with insufficient runway remaining to stop the airplane". When asked if he experienced any mechanical problems with the airplane, he stated no.
