Right. And as I mentioned, I never said anything about spraying it on lawns. (that would be stupid). Also, my reply really had nothing to do with the use of vinegar, I used it as an (incorrect) example for what could be sprayed with and without a license... see? So, yes - if I want to talk about vinegar I will go to the vinegar thread. I think I can find my way there... Thanks for the link, it was informative.
