We drove up to the Roque de los Muchachos. It seemed strange to come up here and not check in at the Residencia. We walked out onto the rocky ridge which juts out into the caldera, and I took the same photos I take every time I'm up there. I think I've photographed every possible view, but it wouldn't seem right to leave without some new versions of them.
We headed back down the road to Santa Cruz. We'd both been victims of the legendary Lionel, who drove astronomers to the top for many years, knew the roads far too well and raced around forest curves in a way guaranteed to induce extreme car sickness. One time after a ride to the top, I felt sick for five days. So I drove down at a sedate pace and got to the bottom feeling great.
