While out geocaching one day, a cacher had gotten a little bit lost in the hunt for one of the caches. He stumbled out of the forest and saw this sign on a nearby highway! He thought he was saved, but unfortunately for him he had no idea how far away it was to his hometown of Peterborough! Can you help our poor caching pal help find his way back home?
Double check your answers with certitude.
Again, the answer will be a number. For example if you come up with eighteen as the answer, the checker will only be satisfied with 18
