Moving dilemma

Recently I accepted an amazing job offer within the same company I work with. My work would involve exactly/very similar to what I have been dreaming to work on - heavy number crunching, talking geek, etc. The job offer could not have been any better except that it does not compensate me for lack of snow.

Anyways back to the job offer, my work would now be out of the Queen City. I am already having apprehensions about moving to a city which is very narrow minded. On top of that, I am moving for the fourth time since 2006. I have made some amazing friends, grew closer to people who I studied with but never interacted much, was part of the various family/friends' activities and finally had a good social network which was not work related. It took me about 2 years of hardwork and sweat to make friends as family.

My apprehensions arise from the fact that I know myself better than most know me. Even though I am a very social person, I am very introvert and don't speak my mind out. I make friends easily but I don't make best friends at all.
