Mark is ok, bit of a cowboy in the past. Like most of us, you calm down as you get older. Has had a traumatic past, no fault of his own. Actually most drivers, trainers I have dealt with have been ok, maybe not great or perfect in any way. Of course, you only know what you know, but you can get a sense of them the more you deal with them. The one's I had issues with have been the "big name drivers". Carry a bit of an attitude, as if they are doing you a favor, and one top 10 guy who beat the shit out of my horse. This was not a lazy horse, who gave his all every race and made some good money. Should have went to the judges and reported it, but you know how that would turn out. Wont be driving for us any more, not even if he was an Uber driver. Probably had more issues with owners who lie and try to sell you a horses that they know is 3 races away from breaking down or in one case that was under the "influence", owned by a big name owner/breeder, actually Mark saved me on that purchase.
