That's pretty crazy. Now that I think about it I recall buying some briquettes labled oak and hickory to grill with and he didnt have any reaction to it. I honestly never realized oak and hickory were nut trees till it was just pointed out.
Yup---I love Hickory Nuts. We have lots around here, in PA.
Oak "Acorns" aren't that Great, but the Deer sure love them!!
