We saw these cows at the end of our hike, near Turville (aka Dibley). When we got to the edge of a field and turned a corner, there they all were, crowded at the gate waiting to talk to us. I guess they'd heard about the lamb rescue we'd performed earlier on the hike, and wanted to see the hero hikers.
One actually licked my hand as I stretched it out:
A big fat tongue, slurping me in gratitude. How nice!
