Nobody actually
needs to spend hours in their small time, enclosed space where they cannot keep
their equilibrium and don't have any control. It would be like being put in the

by the time you got for your final destination.
To keep your
horse in top condition, both physically and emotionally, it is your
responsibility to keep the excursion devoid of tension...
