Coral Springs, Florida (CNN)Columbine and Parkland.
Two high school massacres, two communities changed forever.
Two fateful days, two decades apart. Tragic bookends in American history.
In all, 30 lives lost: 13 in Colorado in 1999, 17 in Florida in 2018.
Hundreds more survived the gunfire. Most escaped the bullets. Still, they carry invisible scars.
Any loud sound can shatter their day: Sirens sounding, fire alarms ringing, a car backfiring. Time has done little to heal the triggers.
Three recent suicides -- two Parkland survivors and the father of a 6-year-old girl killed in a mass school shooting at Sandy Hook, in Connecticut -- only heighten the struggle.ry Stoneman Douglas High School, north of Miami, is 14 months fresh. What would survivors of these twin tragedies have to teach each other?
Four from Columbine agreed to travel to Parkland to meet with four of their counterparts and speak with CNN's Brooke Baldwin at the nearby Coral Springs Museum of Art.
