Granted he also states "unlimited opportunities for learning" which does focus on the Student portion, but...unlimited opportunities is not like x number of hours a week. Maybe just a little spin there? I think what would have been great is whom ever took the position blogged about the experience (with Mr Martin's approval of course) to provide insight both to this specific job, but maybe to the WS approach in general. That whole research thing that Rayers, Deltawave and other smart folk talk about all the time.
The ideal candidate for must be enthusiastic about working extremely long hours, six to seven days per week. The work is hard, and consists of stall cleaning, grooming horses, tacking and untacking horses, and general barn and farm clean-up.
