In reply to galpinos:
There are now many places to go bouldering in NYM with lots of new development taking place (I know this will not help this trip) as new guide due to be published early next year (If deadline is still correct).
You could check out www.betaguides.co.uk who are writting the guide, the website details a lot of the areas and you may even be able to purchase a mini guide to the area you want now!!
Best places I have been to in the moors near to you are Rosberry topping (although the locals say its getting trashed) Ingelby Incline (great place) & Duck Pools (Further away from you though).
The weatehr dont look good for Sunday but tomorrow does. Please becareful when climbing on wet or damp sandstaone.
Hope this helps
Tony
