President's Blog As a relatively older and relatively recent starter I think you are right about "Peak Peal" having being passed. I can't see myself ever ringing peals even if I could, due to time constraints - I'm still working full-time, and expect to be for most the next decade, by which time I'll be in my late 60s. Even QP opportunities are relatively scarce for me and they are long enough for my taste anyway. When I do get to ring QPs my ringing has definitely improved afterwards. But until the last month or so I'd had a 2 year gap (not by choice) so for me it was like starting over from scratch when we rang a couple of QPs of PB6 at practices, when we met short with 6 ringers.
the most prolific peal ringers I know are exactly as you describe - they have being ringing since their youth and are now retired. I think your other observations are on the money as well. Although in the case of my home tower, it's never got beyond CCs for many decades, so I don't think the issues are entirely new.
I was talking to one of the long-standing ringers at a practice yesterday after a touch of Oxford Minor had been rung and he mentioned that Oxford was the basis of other methods such as Sandal, Capel etc. I've taught myself to ring spliced Oxford Group on the tower sim, but I've realised I'll be unlikely to ever learn to ring them 'for real'. He carried on to say "They used to be rung around here a lot, but none of those people are ringing any more". Ringing higher numbers is obviously important, but in many areas even quality Minor ringing is becoming scarce, and if it's a struggle to find 6 people to ring methods, you are even less likely to find 8, 10 or 12.
