This was a cache placed by TexasWriter, way back in 2013. I had the good fortune to both know TW (he is still kicking) and to FTF this cache. As I was traveling the other day I remembered this cache, checked and I saw it had been archived. So, I stopped and checked on this container and it was still there. I added a new log and was back on the road.
You are looking for a Berty Tube. (An enhanced soda tube.) Cachers would do well to remember the Denial signs in Texas. The nearby purple paint denies access to areas just like a fence would. You do not need to pass the purple paint to find this cache.
