I know this festival well...made many pictures from it myself but this is a beaut.
It's from a place called Austin in Manitoba, Canada. Annual festival of vintage tractors that is a goldmine for photographers. (Especially ones with a sensitive eye as here)
What is interesting to me is that these guys appear to have come from the same epoch as the tractor. I get a nice sense of the relationship between man and machine from this photograph. The men seem in awe of the tractor, don't they?
