I'd be happy to sort out a group skills day for you all up at Lee Quarry, although I don't do group discounts for skills days I'm afraid. It would be rather unfair to all the people who come along and pay the asking price.
As for dates, all I have free in October in is Sunday 4th or Sunday 11th. There are however four places free on my Stop Crashing day at Lee Quarry on Saturday 3rd October if anyone is interested. Check out my site for details http://www.great-rock.co.uk
From November I'm running skills days at Gisburn Forest starting with one on Saturday 7th. Saturdays 14th and 28th are free at the moment. As the weather gets worse Lee Quarry can be a bit exposed and the the extra tree cover of Gisburn as well as the sanctuary of The Dog and Partridge will be most welcome I think.
My email is ed@great-rock.co.uk if you want to get in touch.
Cheers
Ed
