After I took a photo of these balls the other week, someone informed me they were lit up on a night and looked really good. So I called back to take this photo and they're right they don't half look good.
Iv'e seen these quite a few times on my travels, so while I was out today I noticed the big fluffy clouds and bright blue sky stopped off to get this photo. Turned it Black and white and used red filter to darken the sky.
