Tonight marks the end of the ancient Celtic calendar year, known as Samhain; a night when the veil between the living and the dead is said to be at its thinnest. It's a night for prophecy and the burning of sacrifices; a time to reap the harvest and prepare for the long, dark winter ahead. So don a mask to confuse any spirits that would do you woe, and gather with your friends and neighbors to drink deeply of your favorite libations while making predictions for the new year. It's time for our favorite holiday. Happy Halloween.
