Y.A.R.N. is - yet another road to nowhere.
All YARNs signal an ending. And there are so many of them out there. I had to stop driving past them and start hiding caches there. Unfortunately, sometimes they do meet an untimely end and become "J.A.R.S." - just another road somewhere. This one does not look to be in any danger of that happening soon. Please be aware that the cache is not exactly at the yarn and the construction should not be in the way.
This, therefore gives me a cache hiding opportunity near one of the most favorited caches in Austin. Please pull off the road completely and watch for traffic leaving the area. Not usually much traffic in this spot, but it is always best to be careful. Bring your own pen, use the hint to make it a quicker find, and always tell the muggles what you are doing.
