Family and friends will mark the two-year anniversary of the incident that killed Johns Hopkins University student Nathan Krasnopoler with a memorial bike ride.

The ride will start at 6:30 p.m., on Tuesday, at the scene of the crash that took his life in front of the Broadview Apartments, 116 W. University Parkway, according to a news release.    

Nathan’s parents have launched an organization Americans for Older Driver Safety to lobby for laws requiring more rigorous standards for elderly drivers to retain their licenses.

Krasnopoler, 20, was hit in February of 2011 when a then 83-year-old woman driving a car ran him over while he was riding his bike in a designated bike lane near Johns Hopkins University’s Homewood Campus.

He died of his injuries six months later after he was left in a coma with irreversible brain damage.

Jeanette Marie Walke, the driver, eventually plead guilty to failing to yield right of way to a bicyclist in a designated lane in May of 2011 and was fined $220.

This is the second year a memorial ride has been held in Krasnopoler’s memory.
