This summer, it was the fence. An old wooden picket-style fence, the varnish was peeling and it was leaning in a few places.
The neighbour adjoining us always complained about the fence - about how he didn't choose to put it up, and how the owners before us had the fence erected on his side of the boundary blah blah. It grew quite tiresome hearing the same story over and over again. So when we approached them about sharing the cost of a new fence, he simply said "No" and then started repeating the same old story.
The neighbour on this side was a lot more accomodating - they were renting the property out but were happy to share the cost of a new fence.
They start by using a chainsaw to cut through the fence and bring the pieces down.
By mid-afternoon they finish.
