It wasn’t all cherry blossoms and a parade in Washington on Saturday. People also watched baseball, ran or rowed in races, raised funds and demonstrated.

Although event-filled, the day seemed for the most part uneventful. However, more than a dozen people were reported injured about 1:30 p.m. when a Metrobus collided with a minivan in Southeast Washington near the grounds of St. Elizabeth’s Hospital.

The bus, on the A 6 route, and the van were both headed south in the 2700 block of Martin Luther King Avenue, when the van attempted to turn in front of the bus, said Metro spokesman Dan Stessel.

He said the minivan driver was cited by D.C. police in connection with an improper change of lanes.

The D.C. fire and emergency medical services department took 15 people to hospitals in three ambulances and a mass casualty bus, said Lon Walls, the department’s spokesman.

He called the injuries minor and not life-threatening.

In another incident, youths were ejected from the L’Enfant Plaza Metro station after pouring water from a mezzanine, Metro spokesman Stessel said.

Organizers scheduled a “K Street 5K” for the afternoon as a “fun run/walk to stop lobbyist bribery.” K Street has been widely identified with lobbyhing. About 4 p.m., police reported that demonstrators were on their way from K Street to the Capitol.

In a separate event, a protest against drone aircraft use was set for Lafayette Square at noon.

Near the Potomac River, foot-race participants raised money for Parkinson’s disease research. In the river, rowers competed. It was unclear if anyone took part in more than one event.
