Lately, it has been overcast and hard to find interesting photo opportunities. However, yesterday I noticed caution tape around a tree. Naturally I took a photo and then asked the guard why they had caution tape up. He said, no they did not think people were going to run into the tree. He graciously explained that the roots are a tripping hazard. I assume the city will build a root barrier similar to the one on the right side of the photo.
Following is a link to a web site called Trees Charlotte; a public/private nonprofit collaboration to grow and diversify Charlotte’s urban forest. Also, a link has been included for today’s photo saved on Flickr with the caption: Caution tape around a tree in Uptown Charlotte.

A reasonable explanation.
