In the 6 years that I've been around COG-Ohio, attendance at rides and wrench sessions runs hot and cold. I've hosted events where anywhere from 1 to 25 people show up. I could never figure it out. Also, the last time that I had access to membership numbers was the beginning of this season and there were less than half the number of COG members in OH than there were 3 years ago.
As for this weekend and my "excuse", well, Sunday had the better weather forecast and I needed to spend one of the two days getting caught up on chores around the house. I served my sentence Saturday, so I could spend Sunday riding.
Also, I have found that I prefer riding alone rather than in groups. Nobody needs to take this personally, as no particular person, group or event formed this opinion in me, it's just what I have come to prefer. Sure, I'm missing out on the socializing/bsing/camaradarie, but I much more thoroughly enjoy my ride.
Add in that there aren't many riding days left and I want to make the most of them, which IMO I can best do by hitting the roads that I know I like.
