Just a short drive from Des Moines is Bouton, Iowa where an old church building has been turned in to a haunted house. It is only $5, and more than worth it. The funds go to the firefighters there (who also operate this haunted house). The haunt has all kinds of stuff in it — dark twisty hallways, creepy folks waiting for you in corners, clowns, unexpected blasts of air … it was a great time.
