I'll be at High Rocks on sunday if you want some decent problems pointing out, wouldn't say I have a vast knowledge of the place but I know where pretty much everything is...(if not how to do everything). Unfortunately they charge for climbing there, but there's no other choice for me as I have a long term project to sort out. High Rocks does have more classics than anywhere else though I think, partly just coz there's more of it! Let me know if you're heading down there anyway.
