I like such games. A time before (when GPS satellites were only drawn on paper sheets) I did an "orientation run" thru woods with compass, itineraire (turn left at fork-shaped tree...) and a hiking map.
And now, there are few caches in my country with such "human" listing (how many stumps there are on your right-hand, do you see stumps or rocks, etc...). I hate such silly formulas with 15 levels of parenthesis or mystery caches that you can completely google out.
Have a nice day.
