Chasing Steers

For four days in a row I've had to entice five black steers out of my vegetable garden back to where they belong - on the neighbouring property. We've had various incursions of cattle in the past because the boundary fences on the land are not adequate for cattle. But that doesn't worry the landowner, the Barro Group - one of the largest privately owned sand and concrete companies in Australia. They expect to be extracting sand on the site shortly but for the past ten years or so they have leased the land for grazing (and growing high value illicit crops).
The guy who owns the cattle has got the message and they have been trucked away to another property.
But it's presumably only a matter of time before someone else puts cattle there and I have to spend a couple of hours a day to put them back.
It's a strange thing that I've never been to work out! If my cattle or horses stray onto someone else's land, I have to run around and get them out. If other people's livestock get into my place, everyone expects me to return them. Maybe I should have a big barbeque instead.
