There are no questions to answer, but you must visit each of the zones along the way and learn about the Qualities of the Canadian Veteran. After visiting all of the zones, you will be given the coordinates of the hidden final geocache. The distance covered will be about 10 km, and should take only about 20 minutes to complete, unless you're biking, in which case it'll take considerably more time...
You can download the cartridge here, and then proceed to the beginning coordinates to visit the zones and find the cache.
