What do Steven Spielberg, Bruce Springsteen former CNN anchor-turned-aspiring politico Lou Dobbs, and New York Mayor Michael Bloomberg have in common? Their daughters all compete on the horse show circuit. In Lake Placid recently, teens Darcy (Spielberg) and Jessica (Springsteen) competed in the junior rings, while Hillary (Dobbs) went head to head with Georgina (Bloomberg) in the jumper ring. Bloomberg is quite the rider. At age 22, she’s the youngest competitor ever to win $1 million on the circuit, according to Hollywoodnews.com.
