When Zenyatta, the 3-year-old superhorse that's been unbeaten in 15 starts, landed in Hot Springs on Tuesday, more than 200 people showed up at the airport, all cheers and signs, including one saying “marry me, Zenyatta” in Sharpie. This weekend, with the Apple Blossom Invitational
on Friday and the 74th Arkansas Derby
on Saturday, is expected to be the biggest derby weekend, in attendance and bucks, ever held at Oaklawn
