The pilot hired the aircraft, a type he had not flown for four years, for a trip to what he believed to be an authorised landing area (ALA). However, he did not check the strip condition prior to DEPARTURE for the ALA. During the takeoff run at the ALA, the aircraft entered thick grass located to the left of a ten metre cleared area along the strip centreline. The acceleration of the aircraft was retarded and the pilot, realising that the aircraft would not accelerate to takeoff speed in the distance remaining, abandoned the takeoff. The aircraft stopped 64 metres beyond the end of the strip after colliding with two fence lines and a road shoulder.
