On a hiking/mineral collecting trip to Virginia one year,My partner in crime and I came across the Bull Run Quarry in Leesburg If memory serves.We ran into some other boys there doing the same.One was an old man that carried a large branch with a flare where the roots were,and inside the little jagged wooden bowl was a large Quartz crystal that he said he got from Arkansas.He kinda reminded me of a Sorcerer,as he not only had the staff he had the look,and the gift for gab.After we talked for a while,he directed his son to show us where to look to find some of the famed little Prenite crystals we had come to find,the young man said look all in here,we will be on that other Terrace back up around the bend and above you.We started looking and it didn't take long for us to find the little green crystals,and when I found a keeper I let out a huge "Tarzan" yell.A moment late a voice from above said "Hey you OK down there" yeah,I replied,I just found a beautiful little crystal,thanks,the voice came again "OK,but if you yell like that again,your gonna have to "Whoop" and old man" From then on,I've tried to be mindful of that lesson learned.I never saw that old man again.
