Cincinnati (once nick-named Porkopolis) had the Big Pig Gig in 2000, with pigs. Most were regular pigs, but maybe 20% were winged pigs. A number of them can still be seen around. For example, the Oktoberfest pig (dressed in German garb) is at the convention center, and the Cincinnatus pig (in Roman soldier's armor) stands beside the statue of Cincinnatus.

Louisville (think "Kentucky Derby") did a similar thing with horses a few years later.
