I am not going to this event because recumbents are not even considered 'innovative' or being displayed, so- sorry. About 15 to 25 years ago a parade and a small museum had "supine, laid-back, unusual or parade" bikes, but I did not take any photos. Plenty of links, but none of this event or the parade:
