I had never seen nor heard of a ghost bike until I saw this thread. I live in Atlanta. Maybe it is not something that has spread every where. I have 4 bikes myself, though, and it just happens that two are white. I like that they are highly visible, especially the newer white bike, it seems to have a fluorescence built into the paint, it absolutely has a ghostly glow at night! But I like the idea that since I already have two ghost bikes, perhaps there will never be the need to have one left on the side of the road for me!
