Jeremy Renner was alone during a snow plow accident that left him in critically condition. Renner was airlifted to a hospital on Sunday after police were called to his mansion in the Sierra Nevada mountains on the border between California and Nevada. The actor was injured while clearing snow in one of his industrial snow plows at his ranch home between Reno and Lake Tahoe. Renner owns a number snow plows he uses to clear his long private driveway as well as roads and paths in his area. Renner lucked out; his neighbor, who is a doctor, rushed to his aid and fixed a tourniquet on his injured leg. Reports say the actor is in critical but stable condition.
