I see drf.com reports that 4 horses have been euthanized at SA since 9/20....I am all for horse safety, but is this the answer? Back in the late \'80\'s, didn\'t RP try a surface called Equitrack? I remember it was around for a few years; wonder what stats they kept on horse breakdowns....back in the late 1960\'s Calder installed something called Tartan track, but I think that was a failure also.
