Fence permit?

No, you cannot install that fence because…

…well, depending where you live, you might think the statement continues, because you don’t have a proper permit.

The passageway for cows and machinery, in which I planted fruit trees that will have to move, included a gate only on the road, leaving the back open. To prevent the cows in the back from destroying the fruit trees, I cut out a section of (useless) fence elsewhere, and dragged it to the offending gap, but I could not install it.

Because immediately two neighbors showed up, and next thing I know they had done it for me.
