The town of 8,000 has been swamped with hate mail and angry calls over Bergdahl, whose release after five years of Taliban captivity in Afghanistan has touched off a debate over whether the 28-year-old should be given a hero's welcome or punished as a deserter.
Meanwhile, the Taliban released a 17-minute video of his handover showing a thin, tense-looking Bergdahl being patted down for explosives by US forces before climbing aboard an American helicopter in the dusty Afghanistan desert.
In Hailey, organisers of a celebration that had been scheduled for June 28 issued a statement saying the town doesn't have the means to handle such an event, given the prospect of big crowds on both sides of the debate.
"If you had 10,000 people, 5,000 on one side and 5,000 on the other, then just due to the national attention, we don't know what to expect," Police Chief Jeff Gunter said.

Hailey Chamber of Commerce President Jane Drussel said she and the organisation have received hate mail and calls from people lambasting the town and branding Bergdahl un-American and a traitor.
"The joy has all of a sudden become not so joyful," she said. Bergdahl was captured by the Taliban after walking away from his unit, unarmed, in 2009.
US lawmakers and others have also complained that Congress should have been consulted about the prisoner exchange, that the deal will embolden the Taliban to snatch more American soldiers, and that the released Afghans will filter back to the battlefield.
