Make sure you watch the road!
THERE IS NOTHING AT THE POSTED COORDINATES. SOLVE THE FIELD PUZZLE TO GET THE COORDINATES.
I was driving by here and I noticed this rest stop off of 390. What's this!? A rest stop without a cache? Well I felt something should be done about that.
But I like puzzles, so I'm going to make you work to get the coordinates. It's not a difficult puzzle. Just try to remember the last road sign you saw before this rest stop, and put the full text into Certitude after you park.

You can validate your puzzle solution with certitude.
By the way, make sure you enter ALL the text on the road sign. If you can't remember, it probably won't be that hard to guess. But if you really can't figure it out, or if you don't have a wifi-accessible device with you, you can get the coordinates from this:
9102785638475093611943057684392017567349826106489027134598376027934816250341596829518264035918670342463
80157312086947146572930420738695
But again, only bother with the number string if you can't get coordinates from Certitude.
Congrats to gr8xpec and mountEverest14 on the co-FTF!!!
