Why are Coloradoans so da*n unfriendly for, especially the ones of the female gender?

I have found Colorado Springs, Colorado to be full of the most anti-social people that I've ever been around in my entire life and this especially holds true for the women here. The women that are here act so stuck up, cold, and unfriendly. In the midwestern states such as Missouri and Indiana, and southern states where I'm from, it is the social norm to introduce yourself and strike up conversations with new folks when at college and out in public in general. If you try to do that here, people will look at you like you are crazy or something. Women don't believe in giving men the time of day here in this city and state. They vehemently refuse to make eye contact with men here and, once again, will look at you funny if you smile at them or act the least bit friendly around them. Back home in the southeast, women would smile and talk to me all the time, and would tell me that I am an attractive guy (no, just because I'm from the south doesn't mean that I am overweight or racist). The last time I went back home to visit I happened to stop at a gas station in Kansas and ran into a lady about my age who was very attractive and A PERFECT STRANGER. She actually smiled and said hello and I in turn said hello and asked her the same. That would NEVER and HAS NEVER happened to me in Colorado. So yes, this anti-social behavior that I've noticed here is limited to Colorado. I don't know why this is true. Do you?
