Farming Oil

Again, this Albertan farm conveys the dichotomy in the provincial economy through sights such as this oil pump. They dot the land on parts hereabouts, grinding away 24-7. To me, they look like steel dinosaurs grazing - or is that the greeny in me having a go at our petrol based economy with its still essentially 19th century technologies?

Either way, the cows don't seem to mind, nor do the farmers.
