You know, I always find these "hey, I'm old enough to be in your forum" kind of announcements to be a bit goofy. Even goofier are the "I'm just about old enough to be here, but do you mind if I hang around?" kind of posts. Being 50 isn't much of a big deal - being a cyclist is what matters.
So, Barry, it's good to have you, but just remember that you should never want to join a group with standards low enough to let you in.
