In March 2020, during the great COVID-19 lockdown, television producer Craig Colby's work disappeared. He marked the time by wearing a different baseball hat every day, posting a picture with a story about each one on social media. A community of friends started sharing their hats and stories, too. After 125 days, Craig ran out of hats, but gained new insight into what each cap told him about his own life. In isolation, Craig experienced triumph and heartbreak, love and loss. He was meeting his childhood sports heroes and floating weightless with an astronaut. The stories in ALL CAPS weave a tapestry of human connection, one hat at a time.
