I travel this way often and I seem to remember a cache here before, but it is not still active.
That just won't do so I stopped today to add a couple more geocaches for all who travel.
You are looking for a micro in a likely place but I woodn't want to give too much away!
Please be aware that you are in Texas and could cross paths with local critters. Never stick your hands blindly into dark places!
And as always, tweeking of the posted coordinates is encouraged and appreciated.
