I stumbled on the coolest place on my way to go backpacking, again because of Geocaching! This trail was put together to teach about recycling. It is at a waste management facility just outside of Salem, so it makes a great leg stretching spot if you are traveling the 5 with kids. The trail has all sorts of fun art made out of recycled items and displays that illustrate things like how many newpapers can be made out of a certain sized tree. Just another hidden treasure I would have never known about if it wasn't for geocaching!
