I had an old friend call me a while back to tell me he was giving up the rat race and taking a job as a ranch hand on the south side of the Rio Grande. He made the decision to let his house and car go back to the finance companies and was going to ride his road bike to his next place of employment, roadside camping along the way. He said he had a spot to bed down for the night somewhat close to me and would let me know when he got there.
I said "Tim, I think you're crazy but confident you will make it work, where is this one time pad you will be staying at?" Tim replied "g lab mozro qspvr uzx v bpn myc fnf wlexc". I was spooked, is this guy psychic? This is the exact location I was planning to place the container for a puzzle cache I was working on!
As with any other cache in this part of the world make some noise and poke around a bit before reaching for anything. There is a spot to park very close to the final location, just make sure you are fully off the pavement. There is also a small rest area about 500 feet west of the final if you don't mind the walk. Please, please re-hide this as good or better, there is a large Border Patrol presence in the area and they are there for a reason.
FTF is free to take one or both of the coins in the container, all others please follow geocaching etiquette and trade even or better.

You can validate your puzzle solution with certitude.
