I belong to ISSCA, for my Impala, and we have a big meet each year that moves around to different spots to be nearer. People in the club also have lots of get togethers all year long though. I am the pres of our local Oregon club, so we haven't gotten together in a long time
. We hang with the Washington club and for awhile here we were meeting about once every month.
Locally there is a drive in, and we have even been welcomed and had a BOSS night (Bad Oregon Super Sports). they even play some old trailers and other related things. I don't see why y'all can't do similar things.
We used to call them "mod days". It all started because there was this brake modification we could do to our cars. It went allot easier with a few extra hands, and so we got like 20 people together and ran each car through sort of a production line with each person repeating a select task.
Eventually we just ended up calling each get together a "mod day" as that is what got us all started.
We have done many different things together though just as people with a common interest. Drive in nights, BBQ, just hanging out at a members shop together talking mods. We even had a day at the go cart track.
I guess my point is, you don't need to have a big centrally located event to have a good time with people of like interests.
