The Caps head into game seven of their epic playoff series with the Penguins at 7 p.m., so Chinatown is going to be a sea of red tonight. Drunk, yelling, fanatic red. At the same time, the annual Candlelight Vigil at the National Law Enforcement Officers Memorial, one of the main events of National Police Week, will begin at 8 p.m. on E Street NW between 4th and 5th Streets. The District Department of Transportation is rightly advising area drivers to stay the heck away from downtown tonight if at all possible. Spectators for both events are encouraged to take Metro. The Gallery Place/Chinatown station is right below the Verizon Center, and the Law Enforcement Memorial is above the Judiciary Square station on the Red line. F and E Streets NW between 3rd and 5th streets will both be closed to traffic tonight for the Candlelight Vigil.
