Big Truck enjoyed an uneventful 1 1/2 mile gallop under exercise rider Kristen Troxell Thursday morning. Trainer Barclay Tagg said, "You have to have a horse that's peaking physically growth-wise and everything else. Sometimes in the spring, when they are two-year-olds turning three, they go through growth spurts and things like that. So you've just go to be lucky that it's all happening on the right day, which is the first Saturday in May. You have to have purse money behind them, you have to have soundness and everything else going for you. It's very difficult."
