I have a buddy who is a classic car insurance agent and car guy with a F1 truck and a model A. In the summer he will hit 4 or 5 events each weekend. Looks at every car, very friendly guy talks to dozens of folks, and passes out flyers. He doesn't stay long at each as its business. So your answer is 20! But he is just attending not setting up.
It depends on membership. All retired guys with nothing to do weekly coffee meets are common. In Atlanta there are the ROMEO guys that meet at the Marietta diner every Tuesday with their cars. They don't do any other events as a group. No tours or anything.
My regional V8 club is almost all old retired guys. One monthly club meeting that includes dinner, one monthly social dinner that I have never attended. And around 3 or 4 weekend driving events a year organized by us and attendance as a group at at around 3 or 4 car shows put on by others. Plus many attend national and regional events put on by the national V8 club. Very active club regionally and nationally, covid excepting.
Most of the ROMEOs are also members of the GSRA, which is a
very large street rod club, that group has one monthly destination meeting, one annual swap meet and one annual sponsored charity car show. The swap and show take the place of a meeting. So one total monthly event.
My SFCC traditional hot rod club has withered and nearly died. We were all young guys with cars. Met each month to drink and be rowdy. Never put on shows but attended HAMB type stuff. Were all older now married, many with kids, some moved away, we all have jobs or run own businesses. Haven't seen many in years. Still meet up occassionally almost a once a year thing at this point. I missed the last one.
If you have a club with working stiffs, members over a large distance, or members with kids who have commitments on weekends attending one monthly event can be a stretch sometimes. Let alone trying to organize more than one or two a year. If everyone is retired you can meet up all the time, if you like each other that much!
