May 25th is Towel Day!

If you don’t know what Towel Day is then chances are you don’t know that you should be carrying a towel around with you today in honor of the late great author Douglas Adams and his brilliant book The Hitchhiker’s Guide to the Galaxy.

If you are a fan of the book, then you know the importance and usefulness of carrying around a towel.

This year marks the 10th annual celebration of this international event. Check out towelday.org to find out about Towel Day events happening around the world.
