Here’s a trail sign we saw over Thanksgiving in Pittsburgh. It’s a explanation of a man-made hollow tree for Chimney Swift birds, which are running out of natural habitat. I think it’s a great way to explain some of the things that were going on around the preserve. They also had a trail sign of the types of flora to be found, and one explaining an area of wetlands.
All of these trail signs were direct printed on DiBond or something similar. That gives a durable yet affordable product. When we do this kind of work, we will coat it with a UV clearcoat that adds to the life of the product.
