If you happen to find a hidden heart in the next month, it’s a reminder that April is National Donate Life Month. Currently, more than 116,000 people are on a waiting list for a lifesaving organ transplant. The Donor Alliance hopes the hearts — hidden all around the metro area — help persuade more people to talk about organ donation and eventually sign up to be donors. One of those hiding hearts outside a library in Aurora was four-year-old Juniper Gelrod and her grandfather, Randy Schrantz.
