I have been a bike commuter for many years. Dublin Blvd is part of my commute route from Livermore. Literally every day, I pick up screws and nails on Dublin Blvd. I do not think you people realize how bad it is. I have spoken with City Street Engineers and they tell me "there is a lot of construction". I do not buy that as being a primary cause based on what I see and where I see it, which is everywhere, even on developed areas. Dublin Blvd is the worst!!
