If you've made it this far, you should be looking at a red sign. What is that sign saying to stop?
Hint: The answer doesn't make much sense. You should have a two word answer. Take the number of letters in the first word and multiply it by 55. This is the number of meters to the cache. Then take the number of letters in the second word and divide it into 60. The answer you get doing that will give you the direction in degrees with your GPSr set on true north that you want to travel. Make it easy on yourself and do this next leg on foot. You can leave your car here.
