Can you see with your nose?

Have you ever noticed that our sense of smell is place-specific? We become accustomed to the way a particular place smells and we don't notice it anymore. I notice this the most at our Roastery. Roastery visitors almost always remark on the overwhelming coffee smell. I have to admit that I don't even smell it anymore, despite the hundreds of pounds of coffee that are processed in our Roastery every day. But if I put one five pound bag of the same freshly roasted beans in my car, I enjoy the aroma all the way home. Isn't that odd? Why do our noses filter out the familiar? Does my nose adjust its filters as soon as I walk through any doorway through which I have previously walked? Does my nose know that I have already walked through those doors? Does that mean that my nose can actually see?
