I wonder at your definition of friends. I keep few friends, and they're all like family.
Now if you mean acquaintances? Oh well hell, just go do new stuff and meet people! Talk to people. It's like meeting the old people, but these are new ones and do different things. Go do yoga and talk to bendy people. Go to a shooting range and talk to Charlie Daniels, etc.
Regional forums would be a bad idea, this forum isn't large or active enough. There would basically be a bunch of dead threads.
