Absolutely fantastic report. Beautifully written, stunning photographs.
There's a lot of what you've written that I can very much relate to, p.ex.
With a few exceptions I have done the munros on my own. I like other people's company very much, but I'm not afraid of my own company either. When walking solo it is easier to be 'on the way' and soak up all the impressions.
It also tests your decision making and gives instant feedback about your skills. When things go well it is a great boost for confidence. When things go pear shaped it is not so great, but you'll have to sort it and hence you'll learn fast. Also, the few occasions when things went wrong definitely increased my (already healthy) respect for the hills, which is never a bad thing.
Yet, the thing I love most about walking on my own is meeting random people from all walks of life on the way and having a chat with them. I probably won't see them again, I have forgotten their names, but I will remember meeting them and that it made me feel part of this wonderful community of lovers of the outdoors.
A'Mhaighdean is a very fine hill to finish your Munros with. It's an awe-inspiring, magical place. I'll never forget arriving up there a bit more than half-way through my Fisherfield "marathon", entirely exhausted, and then being infused with new energy when the amazing view was suddenly revealed to me. I really should start thinking about camping in the wild (too much of a chicken for that) after reading your report. Or about moving to Scotland...
Congratulations for the compleation! I hope you will now tackle the Corbetts, Grahams, Donalds and other interesting hills and write equally beautiful reports about them for us to read.
