So one night, me and Tiff went to get dinner. We walked to this one big square called "Alameda de Hercules" and tried to find a spot to eat. The closer we got to the square, the more people we saw wearing a black T shirt with the above symbol on it and no other writing. I thought some parade or march was going on, or even worse, that there was a cult ritual involved, and no one told me to stay in.
So we went home. And turned on the news. Low and behold, there was a band playing a huge concert that night, and these people didn't belong to a cult, but were leaving the show (like 2 miles away). Still, better to be safe then sorry.
