Very good advice Mark. I've got one of those stories myself. If I told you how many wingbones were in the box, uncovered, no borax, no salt, I mean nothing, you probably would not believe me. Needless to say, I had to go around to the back of the PO to pick them up and upon opening them, they went straight to the trash can.
Like you, I welcome wingbones being sent to me for making calls. It's really simple, clean as much meat off as possible, put in ziplock bag, covered with borax, package in box for shipping and freeze. Mail them on Monday or Tuesday, priority mail and they are sure to get there before the weekend.
Thanks for bringing this to everyone's attention.
