I live in Massachusetts, the bluest of blue states, and we still have special laws about Alcohol on Sunday. According to Gemini, Logan airport can't start serving until 10 a.m. (Because in Massachusetts, we don't want you getting drunk on the way to your Unitarian or interfaith Sunday service after you get off of your red-eye flight.)
