Contiki: Pin Me If You Can
I love this Pin Me If You Can promotion from Contiki by Poke London. Five locals show their surroundings in a set of video clues and give hints about the location. All you have to do is drop a pin on the map to guess where they are—not which town they’re in, but the very spot on which they’re standing.
Like the Contiki page for extra clues then watch the videos which not only give you clues to the location but do a nice job of selling the sights of the area. A promotion that actually does the job of selling the product. A rarity these days.
