Brilliant idea. There must be quite a few places where there are multiple mudcateers.I don't think there's anyone near me tho. BUT, how about posting whenever anyone plans going to a festival or concert they think might interest other cats & perhaps meet up there (or just to advertise the event. That might achieve a similar end for the geographically challenged.
The big folkie fests I know of in my reach are Towersey in Oxfordshire & the big Sidmouth one. Anyone go to those two at all? Or know of any other really good ones?
Best of luck getting a local Chapter going.
