No Red Rings!

I have in the past kvetched about the fact that the combination of red rings and red rocks has the result for poor TV viewers that they may utterly fail to see rocks in the rings, because they are red and sit on the red rings. Laugh if you will, but it HAS happened to me.
So imagine my delight to see this picture of the rings at the Colonial Square Ladies Curling Classic at the Nutana Curling Classic in Saskatoon!
