Solve the numbrix, find the cache
Sometime I'll drive by a place and think "Hey, there should be a cache here". Other times I'll see a puzzle and think "Hey, you could hide coordinates in there". This cache combines both of those.
The numbrix is a puzzle created by Marilyn von Savant and appearing in many Sunday papers. The cache, like the puzzle, has a few twists and turns, just enough to make it worth the trip out to...well, wherever it happens to be. Terrain rating comes from a short steep bit at the end leading to a, literally, breathtaking view.
Update 1.17.12: Cache is now a single stage at the puzzle coordinates, terrain and difficulty have been adjusted accordingly
