Currently I am in the rocky semi-desert on Tenerife, Canary Islands, Spain.

Practically it is possible to live in a tent even in the winter in this place.

I spent the previous winter in my tent. And probably I will spend this winter too in my tent.

So while I live in this place, I do not have to spend money on the heating either (the lowest temperature in the winter in this place is usually around 15 °C).
