To the Editor: Regarding the letter from Peter Goldwasser of Transportation Alternatives to Bette Dewing (?Efforts for Pedestrians,? Nov. 6)?first, I would like to applaud Bette Dewing for her years of hard work as an activist on issues such as noise, bikes and the community. Second, if Transportation Alternatives is the ?strongest advocate for pedestrians,? why is it that nothing has been done to protect men, women and children from the bikers who ride against the traffic, through red lights and on the sidewalk? Several weeks ago as I was stepping out of my building, a man in a business suit, who should know better, was riding on the sidewalk in front of me. I have had so many heart-stopping experiences it is a wonder I am still standing. Bunny Abraham Central Park West Letters have been edited for clarity, style and brevity.
