Northern Michigan is perhaps the most underrated part of the country...to visit.
I worked for a company with their HQ up there, and went up once in September, which was amazing. It was like summer...but no tourists. I went up for a training in early November, my god, the wind off the lake was brutal. Half the stores were seasonal. The restaurants and bars were mostly closed. I was up there for a week, and literally the best place to eat was an Applebee's a half hour away.
