You have two options:
1) If a chapter in your county has a web page, open by clicking on their link. Their web site will have information on becoming a member. (Several Chapters also have an application form that can be filled out on your computer and submitted to their address.)
2) If no web page is available, send your name and address to the Chapter using the correspondence information listed in the chapter detail. Someone will quickly respond to your request.
