For a brief time in the late 80's, I joined a local Alfa Romero club when I'd bought a new Spider Veloce. I enjoyed the club and our social events but what I ended up realizing I didn't like were the rallies. My wife and I would often simply split off and meet up later. These was pre-cellphone days so you couldn't call anyone to say you were separating from the group.
That was a good lesson for me. I do very few group activities although I'm a member of a number of groups. I like my alone time; I see enough people most days to get my fill.
