Cows attack nurse on treasure hunt She was rushed to Lincoln County Hospital, and was said to be in a stable condition after undergoing several operations to set broken bones. She was put in intensive care and put on a ventilator to help her breathe. Andrew Leonard, her brother, later said she was out of danger. Geocaching, which has become increasingly popular, involves hiding a small waterproof box containing a logbook and a pen, recording its coordinates and logging its location on a website. Another "cacher" will see the listing online, enter the coordinates into their GPS receiver and set off in search of it. The code of conduct of the Geocaching Association of Great Britain (GAGB) states: "Respect property rights and seek permission where appropriate." Jen Harkley, the association's chairman, said "News of Sarah's accident did reach us, and we have passed on our best wishes for a speedy recovery. The GAGB aren't able to discuss the accident as we don't know the circumstances or details of her injuries. However, I have sent a message to one of her geocaching friends who is in contact with her family. Ms Leonard's dog, which ran off during the stampede, was found by a local police community support officer and Ms Leonard's brother the next day. A Lincolnshire Police spokesman said "We received a call from a woman saying she had been injured and was lying in a field. She said she had been hurt when cows stampeded and knocked her over. Although she didn't know exactly where she was, within half-an-hour her car was located at North Scarle cemetery, and she was found in the field off Church Lane soon after. The woman was in quite a bad way, with severe injuries including a broken jaw and other fractures.
