A farmer makes a fence out of three cars as a way to say to his neighbors that it was his farm and he could do what he wanted with it. After they moved in they starting complaining:

“The people who bought the homes say, ‘Well, we love looking into your yard and seeing the horses and the cattle, but we don’t like the flies, and we don’t like the mosquitoes,’ and when I cut my field to bale it, they say, ‘We don’t like the dust in the air”

He offered to pay for a fence and would even install it but they didn’t want their view disrupted so he put up the cars as a joking way to remind them that they were in farm country and he could do what he wanted with his farm.
