I have driven past this tree many times through the years, and finally bothered to stop and take a photo. Have seen many more shoes on this tree at various times in the past.
I suppose a big wind or snowstorm could decimate the decorations, as it would with any tree in bloom. Or maybe someone just saw a pair they could not live without!
Do you notice that all the shoes are paired?
I’ll bet that makes it easier to get them to hang on the tree.
I believe I’ve seen similar trees on other desolate roads – though this particular one gets plenty of traffic for a two-lane road.
