I will definitely not miss living in the middle of nowhere with nothing to do during the weekends. I will not miss being one of the 6 persons in the area my age/single/in my situation (I'm teaching at a college while taking a couple of courses as a student). I will not miss feeling lonely (thank god I have a couple of friends who are college seniors and 7 years my juniors). And I will not miss the long, cold winters (although I'm not heading a much warmer place either).
I will miss the colors of the fall in Central New York. I will miss the deer that come to my yard almost daily, or the woodchuck that lives nearby, or the foxes, rabbits and hundreds of squirrels/chipmunks living in the area.
Finally, I will miss my students and my colleagues in the department.
