Some chapters have large quarterly meetings, like mini-conferences.
Usually if you eat during your meeting you can arrange for a meeting place. If you do not plan to have meals available, you could meet at a public building. Some city, state, provincial, and federal agencies allow meetings to be held in their buildings. Sometimes this is possible only if one of the members of the chapter also works for that agency. You can try schools or public libraries, usually there is no meal service in these facilities.
