The black fences and white pickets lining the fields along Route 526
in Monmouth County signal the changing borders of horse farms with
quaint names like White Birch, Fair Wind and Birch Creek.
Dark brown mares and their thick-maned yearlings graze in the
corners or under the shade of the few trees that rise from the rolling
plains. Away from the road, clusters of stables housing hundreds of
horses dot the landscape.
