The Lifeflight Helicopter is scheduled to make a landing Saturday as part of the 911 Emergency Response Expo at Dillon Park here in Woodbury. Although some of the surrounding counties responder units and agencies had other obligations and could not make the Expo, 911 Director Roy Sullivan assures that there will be plenty of emergency response units and agencies on hand. Several demonstrations will be performed throughout the Expo. Mr. Sullivan says this is a great opportunity for the public to come out and learn about the many ways these responders save lives on a daily basis. The Expo takes place from 9A-3P Saturday
