Carlos Delgado speaks about the Rady Children’s Ice Rink at Liberty Station, which is in full swing until Jan. 5. Net proceeds from the rink benefit cancer patients through the Thriving After Cancer Program at the Peckham Center for Cancer and Blood Disorders at Rady Children’s Hospital. More than $2 million has been raised to the program since the annual ice rink started 28 years ago. More information: rchicerink.org.
