Happy Towel Day!
An anonymous reader writes "Douglas Adams died about ten years ago and fans have not forgotten about the beloved author and the importance of having a towel. Today is Towel Day and people from all over the world are holding events to celebrate Adams. Some of the events include: a gladiator towel fight in France, concerts in Denmark & Russia, a march against Vogon Violence in Brazil, and a talk on science in the Hitchhiker's Guide in the UK. A Canadian group even ran a contest to select an Intergalactic Towel Day Ambassador for Earth."
