If it was 6 a year, I would do 2 swaps, 1 speaker, 2 hands on workshop/demos, and one end of year potluck with Rich Ross
You can fit in tank/store tours on "off" months. This club seems to be more about what you do in between meetings and less about the meetings themselves, and I'm not saying that's a bad thing, I would like to say it's a more community type of club but then again there's a lot of bias on that view simply because of the forums.
Swaps - Obvious enough, member swap, and all club swap,
Speaker - Someone who has something interesting to say about the hobby in general, doesn't need to be anything in particular, but they tend to cost money which I'm not sure what the finances hold for
Workshops - Watching a few of the members show off their handyman skills shows that we have a range of builder talent, but we've also had workshops on making fish food, and it doesn't have to just end at building stuff, it could be member given talks about any range of things from various types of lighting for the aquarium to various sump designs, I mean I would absolutely give a talk (i'm a teacher so comfortable with public speaking) and it doesn't have to be 1 member talking either, it could be a tag-team affair with multiple aspects. Basically these are the types of meetings I like the most because they give a lot of food for thought as far as ideas that maybe I haven't thought of.
End of year potluck- Again it's about community, if not Rich Ross, maybe someone or something else, a 3rd workshop? End of year potluck plus make your own fish food?
