Yes, that is a big problem that arises when you travel alone and do not want to bother unknown people, and, as you say, they are not very cool and generally the shots are not to our liking.
I loved the solution your sister offered, that could solve things.
It's good that in this view of the Martial Glacier you found a person who took a really beautiful shot of you, dear friend @lauramica
I take this opportunity to wish you a happy start to the week, may you enjoy it very much.
Good afternoon Luis! Luckily this person was able to capture the picture well, on the Perito Moreno glacier someone took a picture of me and it didn't even come out on the glacier hahaha.
I hope you are well. Thanks for stopping by!
