Buck, the Buck-eye or also as it's know is not worthless, it is said carrying one is good luck.
Back in the fall of 1999 I was going to Arbor Lodge for the weekend (burning trees to cook with what else
) A friend of my wife asked me to bring her one back to carry for good luck. Well within a month she met a fella and married him about a year later.
(A mental image of this fella just came to mind, yep that is just another Ol' Wives Tale, they don't bring good luck, they are worthless.)
