Thanks. Sorted. I was thinking about the fact that I didn't wander all the way back to cairns M and N while I was posting. Must have leapt out of my subconscious or something. I was also mulling over not getting up to O & P too, but they're really hard to get to high up above Doonevaragh ... where's me crampons?
Not to worry. I'll be back there in a few weeks time and I'll get to them and Cairn A as well to complete the Carrowkeel set :-)
