Although not part of the BACDS, the Berkeley Old Time Music Convention (BOTMC), Sept 16–20, always includes a family dance — this year it is Sunday, Sept 20, 11am–12:30pm at the Ashkenaz Music & Dance Community Center and FREE. The caller is Janine Smith from Washington, DC.
Other family-oriented activities at BOTMC include a Saturday morning concert with the wonderful Greg & Jere Canote at the Berkeley Public Library, Saturday, Sept 19, 10:15am.
