I agree with your statement on not everyone enjoying a real challenge and prefering the "safe route", it was strangely obvious on our Country Trax weekend. The one thing that came across in a big way was that if you hold back you are not going to make it! With so many obstacles if you dont attack it from the start it will beat you. In general the "road riders" in our group who were more unfamiliar with dirt used a far more cautious aproach which only resulted in more spills, whilst the crazies with the large gonads just ploughed on through. The ODM looks interesting.
