A hectic Bay Ridge intersection near a public library and an elementary school is giving residents road rage - and a stop sign is all they want."It seems so strange that you have a library that kids go to and you wouldn't put up a four-way stop sign," said Brian Celentano, who lives several blocks away."It just seems so ridiculous.
