But, why not just hold membership in the one lodge you enjoy the most, and just VISIT or affiliate the others that you like?
Some lodges expect a petition to affiliate after a certain number of visits. Other lodges welcome unlimited visits. So it might be a clash of requirements.
Affiliation is full membership in all of my jurisdictions.
I took my degrees in my mother lodge. I paid for a life/endowed membership. I went through the line, experienced consolidations and I'm now a Past Master. Why would I ever demit? I'm at least as puzzled at the idea of single lodge membership as you are at multiple membership. As it is if I ever show up at California GL I get to vote. Since California GL is in San Francisco it's desirable for my wife as well as for me. Plenty of tourist stuff in SF.
At one point we moved the Seattle metro. I affiliated. We didn't live there long enough to go through the line or purchase a life/endowed membership. So when we moved out of state again I sent a demit. I do get that sometimes it makes sense to demit when moving out of town.
Then we moved to Chicago. I affiliated. I went through the line again, experienced a consolidation again, purchased a life/endowed membership again. Now I have a vote in Illinois GL if I go. Demitting would give that up.
Which leads me to why I ended up having two Illinois memberships. I got a job in a different part of the metro area. I started attending a lodge on the way home form that work location. I entered their degree team. I delivered Masonic education talks at all of their Stated meetings. After several years they voted me an Honorary membership. Why would I ever demit from such a gift?
Now in Texas I'm going through the line again, predictably. Once I'm PM and life/endowed member why should I ever demit.
Had I never left town I might never have been a member of more than one lodge. My feet are too itchy for that. Or they were. We'll see at some point.
