Great explorers

A new name can be added to the honorable roll call of Columbus, Roald Amundsen, Shackleton and Tom Maclean (any one who doesn't know who Tom is had better google quick!) all great explorers who set out with a taste for adventure and discovered new lands. Hetty, the Mad Dexter, recently dehorned, has been recuperating in the pigpencowshed, and as Laverne and Shirley, or the best parts of them, are now in the freezer, she has been a bit lonely. Ambrose the potential curry pops in to keep her company but Hetty is on the lookout for a bit of excitement. So today as she was lavished attention, fed from a silver platter, had a fresh bed made for her, a dark shadow stole past as the last of the new straw was carefully laid. Hetty did a runner. Fortunately Hazel the nearly 4x4 was parked in the lane which helped the speeding bovine choose a trajectory that led into the Cauldron. This was all new to her. Pastures fresh. Acres of wilderness lay in front of her. She stood. Sniffed. Stared. William the Welsh Cob whinnied in support. Hetty cast a glance towards him and nodded. Then bolted. She completed the 500 yards in a record time for a mid leg Dexter and ran straight back to her bedroom almost slamming the gate behind her.
Obviously a cow can handle only so much freedom of choice. Or perhaps she spotted the Trolls that live in the caves of The Cauldron.
