BOSTON — Sports championships aren't rare in Boston anymore, and security officials are drawing on what went right — and wrong — during recent victory celebrations as the Red Sox look to claim another title. The Red Sox return to Fenway Park on Wednesday needing one win in the next two games against the St. Louis Cardinals to win their third World Series since 2004. Meanwhile, police are also dealing with a visit by President Obama, who's stopping in town hours earlier Wednesday to discuss his health care reform.
