The signs are pretty simple. It is white 1" schedule 40 PVC pipe and 1/4" HDPE (I think most plastic will do) flat stock. We used stainless steel screws to avoid rust marks. We used weather proof polyester label stock printed on a laser printer. That way as the trails change or exposure ruins the labels I can easily replace them. If I remember right there are about a dozen of them out there and we did it for under $100. We tried to post the signs at any spot where a 'decision' had to be made (go this way or that) with approx extra milage if they take the longer route. Hope this helps. PM me if you want more info
