Ridgefield’s Community Emergency Response Team is holding two drills on Saturday.  CERT Director Sean McEvoy will help teach Boy Scouts how food and water are distributed in an emergency.  The second drill will send CERT volunteers out into Ridgefield to “assess” simulated damage incidents.  Volunteers, wearing green CERT apparel and carrying photo IDs, will report what they find using their cell phones and the Internet.  Ridgefield’s Office of Emergency Management will also be testing new software and radios meant to make information collection faster and more efficient.  Officials say there will be restricted parking around Yanity Gym Saturday morning.  Orange signs along roadsides are part of the drill.
