Robert Porter of Kerrville was treated for minor injuries Tuesday afternoon when he was rescued from his vehicle stuck near a ravine.
The Kerrville Daily Times reports Porter wrote "this was an accident."
Department of Public Safety Trooper James Salaz says Porter was last seen driving near the ravine Sunday evening.
Officials believe Porter, who lives alone, drove down an incline to the pond, but the vehicle couldn't get enough traction to drive out. The car became wedged against a tree. Porter, who had no water with him, honked the horn until the battery died.
A neighbor discovered Porter.
