Our most recent w/end jaunt was to Audlem Bagpipe& Hurdygurdy Day[Sat 6 Nov] but we couldn't camp cos there was a bonfire & firework display on the field & tents prob would/ve melted!
We're currently researching the Cotton Arms at Wrenbury [near Nantwich] which has a 365 basic campsite - water+ toilets, to see if they'll accommodate musicians/siners etc.
We've also been the 3 Stags Heads, Wardlow Mires, Derbyshire recently - another 365 water+bog+washbasin[cold water]which has a freeforall sesh every Sat nite & will also accommodate any other nights as well.
Realistically we're seeking w/ends away within striking distance of Chester-i.e. up to 100miles radius away.
