Tireiron,
I must reiterate what our collieges have said, "you get it" in fact you get it in spades.
Some of the best caches are virtuals. I really like the vituals based in histrory, particularly, obscure history.
Unfortunately, the nay-sayers have the ear of the powers that be, the last several virtuals I tried to post, were denied simply because they are virtuals.
