I noticed some time ago during my weekly trip to Durham what appeared to be a mirror in a tree. Today, the weather was good enough to stop, inspect, and photograph.
Someone had in the past lodged a round truck mirror in the split of a growing tree and now it is permanently captured. The site is I-85, northbound – a hundred yards north of the 166 mile marker between the junction of I-85 / I-40 and the city of Durham. There was no camera attached; so it is probably not a project of the NSA.
