The first time I'd been to La Palma, I didn't know too much about it until I was on the plane to Madrid. My boss had done all the hard work while I was off getting lost on African mountains. Two years later, the situation was very different: I was now the Principal Investigator on a proposal, and so it was much more under my own steam that I returned to the Canary Islands.
By coincidence, I was observing on exactly the same dates I'd observed on in 2001. Then, the moon had been full, and Saharan dust had clogged the air. This time, there was no Kalima, and it was new moon, so the skies were properly dark. But just like last time, the taxi to the mountain top made me horribly car sick. I spent my first night on the mountain top recovering from that.
