A ghost bike for sydney?
 

I'm going to be flying into Denver on Weds, and am thinking about putting up a ghost bike for sydney Weds or Thurs if there's not already one in the works or onsite. Thoughts? Can anyone tell me exactly what landmark or intersection would be an appropriate placement? The ghost bikes here in NYC are a really nice memorial, I think, and I'd like to see the phenomenon spread until it's no longer necessary.
