Snow or no snow, Ben & Jerry’s is calling it for spring on Tuesday and handing out free scoops to all comers. The famously funky ice cream chain has picked a day in late April or early May to give away cones every year since 1979, which marked the one-year anniversary of the company’s founding. The event runs from noon to 8 PM; the Navy Pier Scoop Shop (700 E. Grand) will be the only store in Chicago participating.
