Just in the USA not foreign countries.

I have wondered this because ever since being out of college I have had a hard time running into good looking women. Just talking about the united states btw, not foreign countries. I know that older guys who aren't in the 18-22 age range will struggle a lot when it comes to getting laid in a college town type of area since so many of the attractive girls there will run in very tight cliques (sororities can be a pain in the ass to deal with) and non-students in general would have a tough time. Would like more ideas of places where a high concentration of good looking women can be found.
