Don't know about you, but I did not get to Nationals (2008) but still found that it was on the web. I managed to watch the Halter Obstacles and Driving Obstacles and was quite impressed. For those of you who are not familar with this class, I did capture some video. Hopefully it will work for you and you can see what is involved.
Obstacle rules are in the AMHR rule book, page 266 and can be found at:
