Following Kenr's idea, I imagine folks "of a certain age" could wear a shirt that says " I was climbing before Sharma was born."
But all that would do is invite the question, "Then what happened?"
Anyone who's seen me climb knows I don't need category or tee shirt that says I'm over the hill.
Returning to the point of the thread, glad to hear Dawes et al. hosted a good day's event.
