Years ago I was told that creosote was not good stuff to use. Then I went to Texas where the Creosote bush grows naturally in the Chihuahua Desert. Each plant sends out a message to its environment which basically says "keep your distance, don't mess with me". As a result, naturally growing creosote bushes actually space themselves out, using the chemicals in their system to ward off other plants from growing near them. Modern society now decries a perfectly natural chemical as being bad for the environment. You do have to wonder, so I'll say no more. Somewhere I have a photo of a natural Creosote "plantation" from when we camped out in the desert - something you can't do with any safety these days. Oops, getting political, close the posting NOW. Glad you are using Creosote, Larry!
