Its funny that you say that because everyone I know who has moved/visited absolutely loves it.
I guess maybe it differs in respect to where you are from originally. I am from Long Island, NY. I have been in buffalo for about 5 years going to school. To be honest I am not a HUGE fan of either area. If buffalo didn’t have as bad of weather, I would be SLIGHTLY more inclined to stay. The major factor here is me getting into a professional job in my area at the entry-level. Even IT recruiters in buffalo would admit that it is hard for entry level college grads to start off in buffalo. I visited Raleigh and I loved it. The people down there are REALLY nice, the area is beautiful, most houses are pretty new and relatively inexpensive, and the job market just continues to boom year after year. Add on top of that the ability to go boating on beautiful lakes, hike in awesome state parks, and be on the ocean in < 3 hours and you have paradise.
I am actually really curious, what do some people NOT like about those areas?
