I reckon a day would be suffice, they're all pretty close to each other. Especially if you take rocknicker's advice and don't waste half the day looking for the quarry site like muggins here.

> And would you, Sir Hob, be a willing guide to these dark parts?

Given the chance, I'd luv to. I shall enquire about skiving work. If I can't get as far as Wooler, I could mebbe get to Rothbury for a deeks around Lordenshaws. That's fairly close to the Ladywell at Holystone too if you are still unsated at that point.

PS, if rocknicker suggests you visit the rock art at Morwick, ignore the advice unless you're into absailing ;)
