Over our 26+ years in the mountains of S. Colorado and also here in NC we have seen pretty much the same behavior in people. In S. Colorado people would build a home in our area for the cool summers. We rarely got above 80 degrees and they would move to our area to get away from the triple digit temperatures. It is similar here except the summer temperatures do go up to the high 80's - mid 90's plus the humidity is high making it seem hotter.
Then they would discover that while the temperature is cooler and they would be out on hikes with the wild animals; bear, lynx, mountain lion, bobcat, wolves, badger and a host of animals that were dangerous that city life had not prepared them for this. They had no experience with wild animals except where they are well fed and enclosed in zoo's were different. They would slowly realize that they were a possible food choice for many of these animals. Instead of getting along with the animals they would take a more aggressive approach which does not always work out well.
Then would come winter where our average snowfall, according to the HUD report, we received when we bought the property averaged 264" per long winter. Having to deal with that much snow each winter and wild animals in the warmer months suddenly made city people aware that lifestyle wasn't for them.
Here in NC it is the heat, humidity, bugs and abundant rain that brings some people to the realization that they are essentially living the same lifestyle that they were living from where they left. They venture out on nice days and the rest of their time they spend in air conditioning. Some people are unable to adapt to a vastly different environment. Those who adapt best are the ones who are able to afford two homes - one where they came from and one where they can live part time.
Not all people are suited to a different lifestyle as they are unable to adapt. That is okay with me as otherwise our area would be so full of people that it would be uncomfortable for those of us who can and are willing to adapt. They also tend to bring the very things that they didn't like from where they moved from to the new area. People need to research the area they want to move to before they move to it and consider if they are willing to make the changes it will require.
