Had one in the garden a few years back. It had done a bunk from a herd moving along the road. I was working from home at the time, and looked up to see cow legging it down the garden pursued by three blokes. Took a few seconds to wonder if there was something in the water and decided the sight was real so kept watching.
The blokes thought they'd got the bovine cornered, but it made a dash for it and hurdled a 3 foot fence+ditch to make it into the field next door. Very impressive.
