Midcoast and south are queer dense. Some might say a queer community with a large straight contingent. I would suggest becoming active in social activities like land trust groups, trail maintainers, pro-social causes, benefits for nonprofit organizations, yada, yada. Do what you love and wear and be a rainbow. Get your coffee in Ellsworth at Rooster. Unitarian church in Belfast is a very good bunch of people. Facebook might be a good place to keep track of social events. Bangor has stuff going on. Bar Harbor might be difficult to find energy.
