The MBCA is divided into regions and sections. To affiliate with the section geographically closest to your home, leave the Name of the section to which you wish to be assigned field in the membership application form blank; to affiliate with a different section (e.g. GWS), enter a section name in this field. You can affiliate with more than one section at a cost of $15 for each additional section.

Whether you live in the region covered by the Greater Washington Section, are a former member who wishes to keep up with section events and people, or would just like to affiliate with a large and active section, we hope you will join GWS. Your GWS membership includes a subscription to the Metro Tri-Star, the GWS monthly newsletter which, along with our web site, serves to keep you abreast of the people, places, and activities in one of the MBCA's most active sections.
