I have been in the U.P. and was told to shoot all pork pines they eat the bark off the trees and kill them Have seen where pine trees had bark stripped off all the way around them from about 10 foot and up.
Thanks for letting me know I asked a stupid question...only kidding...I know what you meant. At least we now know there's two of us that don't know what U.P. stands for. I thought maybe United Press but then nah.
