I think I can settle this - several weekends ago I was weed-eating some of our non-mowable property & I had on all the proper safety gear with the exception of a mask. Another player in this story is my very large South African Boerboel - he dosn't like to be seen crapping so he's pretty secretive about it. Here I come with a weed whacker & you get the picture - its like hitting a cow pattie, the shit gets thrown everywhere, including into my open mouth.
I have yet to taste MJ root, but I unwillingly have a point of reference.
I need to brush my teeth again - Now !!
Peace
