I took a bike ride one day on the "Carrer de Agua" (road of water) that used to be an aqueduct in the hills above Barcelona. It's cooler up there, and smells surprisingly piney. Something about it reminded me achingly of San Diego. In the distance you can see the Sagrada Familia, still under construction. That was my ultimate destination on this day, but I never made it. As per usual in Barcelona, I ended up meeting a bunch of people and going to do something else (like eating dinner in an outdoor cafe) instead.
