Spain's most famous summer festival kicked off in the jam-packed and cobblestoned main square of the northern town of Pamplona. People from around the world, many wearing the traditional red kerchief and white shirt and pants, roared their approval as an official on a city hall balcony declared the San Fermin festival under way.

I've always wanted to go o this! Not only does it look like fun, but the element of danger is intoxicating! Let's just hope everyone can stay safe and in one piece throughout the weekend festivities!
