Ken came out to my house to see Zealot demonstrate such a course. The Specialty had 10 entrants for maneuvering carting and all 10 passed. Other breeds have expressed an interest in such a title, and a few have actually competed in the NCA draft test. The test usually takes an entire day to complete. A walk through the course is usually scheduled the day before.
Tests are rare.
For us, the nearest test is once a year, two hours away, in Indianapolis. There is a chain of clubs giving draft tests yearly. Some wealthy or retired folks make a vacation of entering all the tests and driving the circuit. Entrants are selected via a lottery system. Receiving more than the limit of entries by a certain date, clubs draw entries out of a barrel, then draw a list of alternates.
