we are back from our trek now. I don't feel like writing too much right now, because there really is a lot to say. Just know that it was amazing, and an incredible challenge. We walked almost 200 km's and went from 740m to 5416m and then back down to 800m. We couldn't see mountains the whole time because of cloud cover, but we saw glimpses at least of every one we passed.
And of course there is the great news of our engagement at over 5000 meters! I will add some pictures slowly as there are many and the internet never seems to be fast enough.
