From the Wall Street Journal:

Less than four years after the last equine slaughterhouses in the U.S. closed down, an unlikely coalition of ranchers, horse owners and animal-welfare groups is trying to bring them back.

The group, gathering in Las Vegas this week for a conference called Summit of the Horse, aims to map out a strategy for reviving an industry that slaughtered as many as 100,000 horses a year in the U.S. before it was effectively shut down by congressional action in 2007.

Advocates say the slaughterhouses could bring an economic boost to rural areas and give owners who no longer have the means or inclination to care for the horses an economical and humane way to dispose of them.
