Student caving culture comes in waves, as generations of members come and go with high turnaround. If you'd tried to draw this chart at CHECC in the year or two before Covid, when ULSA/SUSS formed most of the CHECC and BCA youth committee, you'd have something that was pretty much completely flipped, even ICCC were fun - well aware of their rock-bottom status they regularly sent envoys up north to successfully build their rep. Same goes for the adult clubs, you might as well just draw a list that says "My list of friends".
Though we can all agree York are the least fun, regardless of era.
