In short: I made a new friend after being stuck in a village for a full week due to rain and road washouts.
10 years ago, I travelled solo around Chile and Argentina.
I was on the bus in the Atacama Desert, going to San Pedro de Atacama, when it started to rain. Pouring rain. In the Atacama Desert. Hmmm...
Soon, water was covering the road... The rainstorm eventually stopped but the bus soon came to a halt, with emergency services people climbing aboard and telling us that the road ahead was washed out, but that we could step out of the bus and walk the remaining 3 km to San Pedro de Atacama on foot if we wanted.
So, off I went. A deep gully ran across where the road once was, but the staff kindly helped us lower luggage down as we clambered. Up on the other side, drivers coming the other way had no choice but to turn back, so getting a lift to San Pedro only took a few minutes.
That was not quite the end of the adventure, though: there was no power in the village and thus no streetlights of any kind, and since I did not arrive at the bus station and did not have a smartphone back then, I had to rely on the very vague cached copy of Google Maps on my tablet to find my hostel.
Chilean crews soon built an emergency track to bring supplies to the village, but that was only for light vehicles, and I had planned to take the bus to Argentina three days later. After many false starts and rumors, it took 8 days for the bus to show up. Thankfully my schedule was not tight at all...
In the meantime, since everybody was stuck too, I made a very good friend in the hostel. We ended up travelling together in NW Argentina, and we keep in touch to this day - she lives in Italy.
Also, the delay meant that I arrived in NW Argentina just in time for Carnaval, and that was quite the party!
