Welcome to On the Radar, where we preview upcoming events to mark your calendars for. Your heart belongs to daddy, so show the old man some love this weekend, all for the low, low price of free. (How’s that for a father figure?)

At the Tampa Bay History Center’s Father’s Day Watch Party, you and Pops can get heartwarmingly old-timey and catch a game of afternoon baseball displayed on a 20-foot LCD in adjacent Cotanchobee Park as the Rays take on the Marlins. Kids will be able to occupy themselves with fuzzy blue mascot Raymond, the Rays street team, batting cages, Nintendo Wii consoles, and a craft area. Dads get in free to the History Center with one paid admission and can register to win a VIP Rays Experience that includes tickets to a game, player meet-and-greets and on-field passes to watch batting practice. The Lowry Park Zoo, MOSI, Florida Aquarium and Henry B. Plant Museum are also letting in daddy-o gratis this weekend. Be sure to
