Absolutely sensational. I have never been, on foot, to such a high elevation. You deserve huge congratulations.
I know there is little chance I would ever go there, in fact few of us ever will. Your TR gives many of us the chance to visit by proxy and it is so appreciated. This is a TR to just wander through, quietly, with a nice cold beer etc. and just take it all in. Thank you
Thank you. Still much more to come ;=) But this IS not as hard as you might think. Hiking itself is non-technical (i.e. your Elphinstone might be harder in strictly technical terms). Altitude is issue, but you acclimatize. And it doesn't cost nowhere as most think; flying is only major cost, but with enough diligence (air miles, shopping around, shopping early etc etc) that can also be managed. And then Nepal is still dirt cheap. I will have at the end of post --- which is still nowhere in sight, lol -- some sort of breakdown in terms of gear, logistics, prices etc.
(And no, you are NOT too old in your 60's for Annapurna or Nepal. Trust me)
