I just ring the bell and safely ride around them. I agree with the speeders and hollering on your left because even on my bike by the time I hear it and recognize it i am looking at their backside already. It would be nice if the walkers wouldn't walk three and four wide from both directions. They always seem to meet at the time I'm going to pass. You would almost think even with out the bell the ones walking toward you would have sense enough to make a way for you to go through.
