Ask a Freemason you know about it. Don't generally expect a Freemason to ask you. The general adage is "To Be One Ask One".
If you don't know any Freemasons, feel free to contact us and we will have a committee of members from the Lodge contact you to arrange a meeting. If the meeting is of mutual satisfaction, you will be requested to fill in the form for admission.
Your request will be balloted for membership of that Lodge.
All being well, a date would then be fixed for your admission.
Initiation fees vary and your annual dues are minimal compared to the experience you receive.
