Volunteers generally receive free admission to events.
The bands are paid and the halls are rented but the people who do the organizing and other work are not compensated. The two favorites, the Commodore Barry Club and the Germantown Crickett Club, are perfectly suited but on occasion are unavailable and alternative sites are sought. For photos of the Commodore Barry Club, click here. For photos of the Germantown Crickett Club, see the slide show on the PSDS Main Page or the directions page.
