This weekend the fun-loving folk down at City Museum are throwing another party, with a retro theme that only locals could truly love for all of its subtlety and grandeur. The museum's World's Fair Days will be held from 10 a.m.-5 p.m. both days this weekend; the events are modeled after the attractions at the original 1904 Louisiana Purchase Exposition. Where the World's Fair had a life-size elephant made entirely of almonds, at City Museum you'll be able to make an elephant entirely out of packing peanuts. Where they danced the hoochie-koochie, you can be a "tootsie-wootsie" as the Aalim Dance Company shows you how to dance like they did back in the Gilded Age. In 1904, the fair had both camel and elephant rides; Joey the Camel will be on hand for your admiration, and there will be carriage rides along Lewis Avenue. For that 1900s feel in the air, Scott Joplin's ragtime music will be played by Jan Hamilton Douglas. If you get hungry, the museum will have hot dogs cooking, instead of the fare that gave the Fair's aboriginal exhibits such a grisly reputation. The museum will have its own version of "the Pike," the Fair's mile-long track of entertainment and exhibits: World's Fair Days will feature carriage rides, fortune tellers and who-knows-what else at 15th & Delmar. One of the greatest contributions to the modern world the ice-cream cone was born at the 1904 Fair, and there will be no short supply of them at the museum to cool you down as you make your way through the Pike in the same summer heat that fairgoers experienced at the beginning of the century.
