Even though we did see snow just last week, the tulips really are peeking through the ground – a sure sign of spring. Another sign that the seasons are definitely a-changing is the impending start of baseball season in the Windy City. The City of Chicago and National City Bank celebrate the beginning of America's favorite pastime with 'Play Ball, Chicago' on Wednesday, April 8 from 10 a.m. to 3 p.m. on Daley Plaza. Fans of the Chicago Cubs, Chicago White Sox, Kane County Cougars, Windy City Thunderbolts, Joliet Jackhammers, Schaumburg Flyers and Gary Southshore Rail Cats are all invited to join in the fun with free activities involving baseball inflatables, picture booths with photo scenes of Wrigley and U.S. Cellular Fields, batting cages, speed pitch, fun giveaways, team mascots and more. If you're a South Side fan, test your Chicago White Sox knowledge with Sox Trivia held from 11:15 a.m. to noon, hosted by White Sox announcer Ed Farmer. If you're an 'American Idol' wannabe, try out for a spot to be one of 10 fans to sing “Take me out to the Ballgame” in the Cubs Karaoke contest with Garry Pressy at 12:45 p.m., for a chance to win tickets and an on-field experience. Bring your autograph pens – you might see some of your favorite players milling around the premises. Call 312-744-3315 for more details, or visit the City of Chicago special events web site.
