Residents of Secaucus should be aware of an active shooter drill scheduled today.

Although it's only a drill, the response by local law enforcement, fire and medical personnel will appear real.

But again...it's only a drill.

The training is taking place at the Secaucus Public Library on Paterson Plank Road which will be closed during training.

Make plans for an alternate route if you normal drive takes you along Paterson Plank today.
