Conference Alerts is another good site that carries listings for academic conferences, conventions and events. There is a long list of conferences throughout the Los Angeles area, plus you can arrange to have your Conference Alerts listing added too.
We have chosen the listing to be specific to Los Angeles, but you can search other areas and nations too.
There are some listed there I would like to attend myself!
