Alexirob posted this info about where you can meet Billy:
Hey LabRats fans, Billy Unger who plays Chase is joining Radio Disney on June 24, 2012 at the Kauffman Stadium.
Kids can get an all day pass for The Carousel, mini golf, bad run, batting challenge, and pitching mound for only $10.
Radio Disney will be there with games and prizes. Billy will be meeting fans, taking pics and signing autographs!
Not sure exactly when Billy will be there but I’m pretty sure it will be between 11:30 -1:00
