What happened
During the takeoff roll, the pilot determined that the aircraft would be unable to clear trees located at the departure end of the runway. In response, the pilot aborted the takeoff.
The pilot was unable to bring the aircraft to a complete stop within the remaining runway distance. The aircraft subsequently exited the runway, traveling through high weeds and contacting a ditch that had been obscured from view from the runway surface.
The departure end of the runway consisted of dirt and was bare of grass due to frequent landings. The pilot noted that he was accustomed to performing takeoffs in the opposite direction, where obstructions at the departure end were not as tall. At the time of the incident, the aircraft was approximately 65 pounds under its maximum gross weight, and no mechanical difficulties were reported.
