Long before we bought our house, our - now deceased - neighbor planted a pear tree at the edge of his property because he loved pears. His widow did not care for pears and did not mind that her neighbors on either side picked the fruits from the tree or the fallen ones. Our resident groundhog took care of the rest of them. I was all too happy to eat pears that were guaranteed organic--and free.
The other day, a suveying team put stakes on the property and - lo and behold - it turned out that the pear tree is actually on our property! So, while we lost a corner of our garden to a hillslide, we gained a pear tree. Such is life!
