To bad because the dirt track at Rock Rapids, Iowa is the best kept secret of really racy little joints. The thing used to be an old half mile horse track and was shortened to a 3/8 in the early 1970's. The track configuration now uses both the front and back straightaways from the old half miler which presents two really wide and long sweeping corners. It also has a historic tweak as the wooden covered grandstand is possibly the oldest in the country with a 1889 construction date.
