City Hall officials say they have been inundated with emails and calls, both of general interest and protest, since Bergdahl's release.
"National media attention on Hailey and this event has led many across the nation to believe that the event is intended to be a military parade," officials said in a statement. "There is broad interest in this topic, as evidenced by the approximate 100 correspondences per day received by the City of Hailey this week."
"The organizers and Hailey expect a significant increase in attendance to this event, by people who both want to support or protest against it. In the interest of public safety, the event will be cancelled. Hailey, a town of 8,000, does not have the infrastructure to support an event of the size this could become."
