Horseshoes are all about protection. Believed to ward of evil people have been hanging these above their entrance of their home for good luck since the middle ages. Many believe that it should be hung in a "U" shape. All the good luck would then stay inside the curve of the shoe. But, there are those who choose to hang it the other way, believing that when you walk under it, all the positive vibes will "rain over" them. Bring on the good vibes!!
