Opening day for our Major League Baseball teams. Fans attending the Cardinals’ home opener in St. Louis are urged to get there early. Security will be tighter because President Bush will be there to throw out the first pitch. And parking could be a problem for some fans, too. Construction work on the new ballpark is eating up some former parking areas. The Cardinals play the Milwaukee Brewers with the first pitch at 3:10. First pitch for the Kansas City Royals is scheduled for 2:10 this afternoon at Kauffman Stadium. They’re playing the Chicago White Sox.
