A model course will be available Friday afternoon from 2:00 to 6:00, and Saturday before your start from 9:00 to 11:00. The model course is on a representative portion of the map, unused for courses. The control sites will have stands with flags but no SI units.
Download the model map and print it yourself.
There will be professionally printed versions of the map available at the (unmanned) tollbooth as you come into the park, Friday (2-6PM) and Saturday (before 11AM).
