In previous lives, my career came with great travel perks. Corporate films meant scouts and on-location shoots around the world. Writing “The Drive: Searching for Lost Memories on the Pan-American Highway” was the vehicle itself for a year-long road trip. I’m a Bruce, as in Robert The (wink wink) who’s always wanted to trace my ancestry in Scotland. But the pandemic clipped my wings. Until now. Thanks to vaccines — plus advances in testing, rigorous contact tracing and a country that truly cares about all vaccine-preventable diseases — I’ve found the spot my great grandfather memorialized almost 100 years ago. So grateful to DNA and mRNA.
