Howdy. Cherry Creek does not allow tracers or "penetrator" rounds, although they recently changed their rules to permit M855 green tip 5.56 rounds (thank goodness). Although I would love to shoot tracers, given that Colorado (especially the Front Range) is experiencing severe drought and dryness, I wouldn't it consider safe to shoot incendiary ammunition anywhere in Colorado until we get more rain/snow. Unfortunately, we'll just have to wait patiently for Mother Nature to provide more precipitation before thinking about tracers. Even then, I am not aware of a "legal" place to shoot them, as I just haven't done enough research. Maybe other folks could contribute to this thread?
