Nice thought, but I'll play the devil's advocate,, I'm like that you know, always coming up with what's wrong with it, or why we shouldn't do something,,,,, not that I'm against growing, but it has some issues.
I guess we all want to see events, groups, meetings,,, what ever,,, grow. That means people like what's going on and ask others to join in, and that means that the organizers did a good job,, kind of like a barometer like. Thing is, I like it small, that way way I get to meet and spend time with a more intimate group, we get to know each other better, we share with each other more,, we're more like family.
I have no interest in attending Friday 13th, Americade, Sturgies, or any such big gathering. They have an attraction for the reason that lots of folks attend and there is a lot there, but no interest for me.
I can see the reasons for your suggestion, and have no issue with that, but I think we'll also loose our identity. Having more folks attend a rally is no attraction for me, I enjoyed what little time I could be there this year and hopefully next year I'll get to spend the whole time there, but if it becomes a mega gathering I'll figure there's enough folks there already.
Just my thoughts.
