One of the folkloric sayings I studied in the Folklore class I took at the University of Virginia was the old idiom: "Good fences make good neighbors." May I add, and this fence rocks!
Fences, and forms thereof, have been the source of many things - property rights definition, containment, borders, lawsuits, fueds and even wars!
Much has been written about fences and neighbors - and whether they truly make good, bad or indifferent neighbors!
Well, it seems to me that it depends on the fence!
Here is one for the ages!
And so, can you tell me - what kind of a neighbor would this fence create? The words wacky and zany come to mind!
The construction of the fence is as bad as you are imagining. The horizontal members are nailed with one nail into the posts, and tree! The posts are buried in that small cement block, but the block is merely resting on the ground! Yes, this fence rocks, so to speak! It really does rock... The posts holding the one gate (!) were buried in the ground, but I could rock them easily so they may have been only about 6" deep or so. And the fence is delightfully fitted to the tree!
My recommendation: when the property description comes with the phrase "fenced in rear yard," and there is no photo to show you what that means, you might take it with a grain of salt. Have a look see before you decide that is a good thing! And be sure to meet the neighbors! Like that other folkloric "box of chocolates," you never know what you might get!
