Hi Barb,
You are doing it just how it should be done. Put up a post here seeking interest and then run with it. We encourage members to do this in their local areas, we have one here in Melbourne Australia every couple of months where we gather for cars and coffee on a Saturday morning.
So if there are others here in the Group that would like to get together, other than the biannual PUB or alternate year Euro Tour, it is up to and members to get off their butts and do something about it, it does not happen unless some one makes it happen.
Go Barb.
Garry
