One afternoon last week a stunningly gorgeous cumulonimbus cloud was building over Calgary, towering over the downtown towers.
The thing was alive – if you stopped long enough to watch it, you could see the cloud tufts grow and move like an organism, or like a floating cauliflower on steroids. It had an eerily nuclear appearance to it.
As soon as we got home I dashed out on my bike to find a good place to catch a few shots of it dwarfing the downtown core.
