n.— «The jollity can be laboured, too. Parade marshals now taking up position on Duval St are called “madness ambassadors.” We “robed revellers” are exhorted to be “frolicsome” and enjoy the “menu of mania” on offer… before being warned of the activities forbidden “within the designated fantasy zone.”» —“United States: The bare truth about a fantasy island” by James Bennett in Key West, Florida New Zealand Herald (Auckland) Apr. 6, 2007.
