Thorns

So I had just gotten finished getting my bike tire repaired from being punctured by a very sharp thorn when I came across this tree. Same thorns that went through my tire and into my tube. Only, this tree (and others like it) was planted in the middle of a sidewalk! Who thought it would be a good idea to plant a tree with long, sharp thorns that sits about head-level for pedestrians on a walking path?? Genius I tell you! Genius!
