I am looking for some feed back on an idea that I have for putting up posted signs. All the conventional ways with some kind of post with or without a plywood backing are expensive and labor intensive. The use of nails is prohibited by most landowners and just doesn't last. I'm thinking of a system that could fit in a back pack, signs, tools and this system of attaching the sign to the tree, that would be inexpensive, easy to use and transport, doesn't harm the tree and would last until the tree fell down. Without disclosing to much, I'm just wondering if people would be interested in such a product?
