I found the stones in this photo interesting. To take the photo I had to sit on the ground and use my tripod lowest level. Note that the building on left of the photo is a great restaurant called Sassafras Southern Bistro. I will work at finding their web address and update this post when I do. In the mean time their phone number is (864) 235-5670. Click here to see a Google map showing their location. 
In the comments on this post, Anne asked if the stones in the pavement are really green? So I have posted the photo on the left taken during the day. In daylight the stones are red and a little blue. Yet in the photo taken at night, with a very slow shutter speed and fog in the air, the stones appear green. Maybe another photographer can explain the effect. I will do some reading and if I come up with an answer it will be posted. Also, note the greenish tint on this other foggy night photo.
