Considering the facility is in a metro area, and the obsession with PETA to have horses retired from all forms of use, especially in public, city settings... I think digging for dirt and pre-emptively seeding negativity about a facility you have nothing to do with or any true interest in is rude and irresponsible. Businesses work hard for their reputations; and thoughtless, baseless comments like yours can negatively impact them.
It's a lot like nuts and bolts - if the rider's nuts, the horse bolts! ~Nicholas Evans
