Forest Park Casket Races
Time Out says
Outfit a "casket" (or a casket-shaped cart with wheels) in your favorite decor for this spooky annual race through the streets of downtown Forest Park. The rules are simple: A helmet-clad "ghost" rides inside the casket, while runners push the contraption as fast as they can along a 585-foot course. Prizes will be awarded for casket decorations as well as for the winners of the race, but try not to worry too much if you're not particularly athletic—there's also a prize for the "dead last" final finisher.
