There is a Thursday night jam in Chatham from 9-12(or so). It rotates from house to house each week and has been going on every week since 1986 with only 2 misses (weather). Last week there were 6 guitars, 2 banjos, 1 mandolin, 2 fiddles, 1 electric bass, 1 conga drum, 1 chickenshake, 1 dobro. Lots of bluegrass with some country/folk thrown in. This info is from a friend who plays in this group. PM me if interested in making contact.
