Great Raamahn Herbs
Ezekial chapter 27 tells us that the city of Tyre used to be an important trade city ... where people would go to exchange precious metals and gems for herbs from Raamah ... Really?? Those must've been some pretty awesome herbs!!
As far as I'm concerned ... any herb that can make my noodles taste good is worth it's weight in gold! ... And any metal that keeps me from danger is precious!
You're looking for an herbacious micro guarded by precious metal.
And remember ... Geocaching is the spice of life!
