[IceHorses] mineral levels

[Barbara Sollner-Webb]

dear friends,
    i thought you might enjoy looking at this valuable link, given on  
the EquineCushings Yahoo group, that shows the level of different  
minerals in your area.  (of course, this is real useful for guessing  
what is low/high in your hay!)
