After driving past Zapatierna, we kept going up and up. It was our windiest, and coldest daytrip yet. It was also the one with the most tricky driving. I tried to reduce my chirpiness to a minimum so that Raquel could concentrate behind the wheel. In this very stretch, an alert Mrs Z began to notice patches of dying/dead pines. An invasive species of butterfly had been nesting throughout. The firs and beeches seemed resistant so far. the poor pines not so much. A problem for forestry personnel.
