We start with a discussion of a type of coronavirus testing maligned after it turned up a spate of false positives in Manchester last week. Ryan Ferris, CEO of Garnet, which markets the rapid COVID antigen tests, and Russ Scully, a Burlington area restaurateur whose employees use them, talk about their usefulness. Later, Green Mountain Community Fitness, formerly First in Fitness, in Berlin, has, like a lot of businesses, been struggling in the pandemic. Owner Nick Petterssen talks about high hopes when he and his wife Cady Hart-Petterssen bought the business in January, and their troubles since then.
