I came across this link at one of my favorite comedy sites, Cracked.com.
It's a comedy site, but it's based in fact, which makes it super interesting.
This is a random compilation of crazy festivals from around the world. Guess what? 2 out of 7 are in Spain.
My favorite of this list is definitely the number one, which talks about burning sardines (which I wrote about in my Alicante blog), ant-filled mudballs, flaming madness, people dressed as cows, etc etc.
I haven't heard of this city nor do I know where it is, but it seems like typical Spain to me.
