Who: Retired teacher Bruce Clark, 64, of Waterville. He and wife Cathy own and operate the Blue Rooster artisan bakery.
What: Hunting for geocaches — hidden “treasure boxes” — using high-end GPS and gut instinct. It’s the hobby of a baby boomer (he’s on the leading edge of boomer demographics) who 20 years ago learned to write computer code, mostly Java script and HTML, for customized programs. Now he designs graphics and posters, writes accounting programs and has experimented with movie-making and 3D modeling.
