At 0830 central time, a Mooney M20K struck trees during a go-around at Birdwin Airport. The pilot and three passengers were not injured. The pilot said he overflew the 2,200-foot turf runway 03 prior to landing and noticed no hazards or standing water. He made the second approach and landed, but the airplane was not slowing down. With heavy braking the airplane started to skid. The pilot abandoned the landing and applied full power. During initial climb the left wing struck a bush. The airplane pivoted to the left and struck an embankment.
