Arboretum coordinator Elaine Fingerett, right, and Patrick Foley, a vet school statistician, joined other fiddle, guitar and banjo players for the Arboretum Folk Music Jam Session on the Wyatt Deck on Sept. 18. Created by Fingerett almost three years ago, the biweekly jams give campus and community folk aficionados an opportunity to play together over the Friday lunch hour.
