in case there are any other rockville residents reading this: Dawson's Market, in rockville center, will start filling growlers "very soon." they have the equipment in place, just waiting for their growler bottles to come in. MoCo law says they can only fill "containers branded in the name of the license holder" so that means that can't fill external growlers... but the guy i spoke with wondered aloud if putting a Dawsons sticker on your growler constituted "branding".
