Portlandia, for a while. Never got more than about a third of the way down the coast. The rainforest along the coast range was always a magical place for me, like full of life (where it wasn't all cut down).
The Dudleyas here love places like the ones in your pictures where they can colonize a rocky cliff (or highway cut) and they don't seem to have much competition. I suspect they get a lot of their water from the air. The growth rate in nature must be a tiny fraction of what we observe in cultivation.
