In the end I was glad to stay today, and I'm also glad to leave tomorrow. There were local festivities at Cervera. It's reminiscent of the fiestas of certain pueblos of Mexico, but I haven't attended enough fiestas either in Spain or in Mexico to have an informed opinion.
I worked a bit in the morning, then went to the gym and to the pool. In the evening I met up with the Mexican acquaintances I've made here (wonderful people!) to enjoy the fiestas.
