Let's add Lunenburg's Folk Harbor Festival in Nova Scotia, usually held the 2nd weeken of August. It's a great example of cooperation of a small but beautiful harbor town and folk music organizers. There are concerts and workshops on the wharf, the gazebo, the opera house, and a large tent on Blockhouse Hill, and informal singing and playing far into the night. My favorite memory is of my first sighting of Tanglefoot singing their pirate song "Traighli Bay" on the wharf.
