We frequently ride a set of trails with lots of blind curves. When approaching these curves, I always signal my presence to any unseen riders on the other side by calling out "Bike Coming". My hope is that anyone on the other side would call back so that I know they are there and I can take appropriate action.

The problem is that no one ever signals back. Twice now I've been gritched out for not yielding to an uphill rider that I didn't know was there until it was too late to totally yield the trail. I think that part of the problem is that the phrase "Bike Coming" implies to riders on the other side that I'm aware of their presence. They then assume that I'm being rude or ignorant by not yielding when they're riding uphill.

I need to change the way that I'm signaling. I'm thinking of calling out "Blind Curve" but the simple act of proactively calling out may still imply to unseen riders that I'm aware of their presence. I've considered a bike bell but I'm not sure that the sound would carry far enough.

So I'm wondering if any of you signal proactively? If so, how do you signal?
