Jaye - as a farrier, what is your gut feeling on 
    the causes of lameness in endurance horses? I read once that over 3/4 of the 
    lamenesses in performance horses (not necessarily endurance) could be 
    attributed to the feet. You have an exceptional eye for gait irregularities, 
    and I know you have spent a lot of time watching horses move. Does this seem 
    like a likely estimate? It sure seems that on courses like the one in Spain, 
    that are flat and primarily hard packed trail or road - that the foot would 
    be the first thing to feel the effect...
