Miskin used to be magic!
Good Intent at Sweeps is lots of fun.
Tenterden was rain stopped play this year and it really needs more space in the Woolpack - the old venue (was it the 8 Bells?) now alas a poncey restaurant (but not as poncey as the Vine) was better but still very cramped.
Piggy is great.
About 30 years ago there used to be a range of unofficial "stages" in the campsite at Cambridge and they were great too. You could sing all night if you had the energy. But it was a folk festival then.
I've usually enjoyed Deal, at the Bohemian.
One of these years I will get a full week at Sidders - the bits I have been to are mostly excellent apart from the pissheads who ruin the Bedford and the Americana and the ARSS at the pub closer to the river the name of which eludes me.
Ely could do with more participation.
Wheaton Aston I dropped in on once and liked a fair bit.
Broadstairs till needs better to provide for participative music.
I am likely to be looking for an alternative the weekend of Chaversham.
