I hear many people that move here to Las Vegas complain about how difficult it is to make friends in this city. I hear that people are mean, too distant, self-involved, tricky, flakey, and just plain unfriendly. In all honesty, this is one of friendliest places I've ever lived. However, those people that do stick around for long haul do tend to develop a certain way about them that is unique to culture developing in area.
I've noticed that Las Vegas consists of one class of people with pockets of cliques. It's more of a corporation than it is a city. This class of people consists of those that have been here a while and feel a personal stake in success and growth of area. The cliques are usually small groups of people from same hometown or similar interests.
However, when you do move to Las Vegas, there are many things that you can do to locate people like yourself. The most popular way is to start a special interest group! You would be surprised at how many people will show up at one of local bookstores for a meeting to discuss group plans. However, I've found that groups last for a short time as people tend to settle in and begin to move on to other things.
Moving on to other things ... an important point to remember. For every five people that move here, one goes bankrupt, another can't handle some aspect of city, and a third stays, but remains angry at city. The other two move on to other things and succeed at one thing or another.
One thing that people don't realize is that The Strip is only a part of city. Las Vegas spans a rather nice-sized area and is expanding in all directions every day. Not to mention fact that numerous industries are poking around at possibility of moving here because it is so much less expensive than many people realize.
The main issue I do have to warn you about is medical community. Your best bet is to maintain contact with your doctor from your prior home as you will find that Las Vegas doctors leave much to be desired. If you don't have a doctor, Arizona and California are nearby and have some reasonable medical practitioners.
