I love when Halloween rolls around! Candy and costumes galore, even though I am not really into the blood and gore.
Halloween is a fascinating holiday, with Celtic, Christian, and Pagan roots http://en.wikipedia.org/wiki/Halloween. In the United States, the holiday was not introduced until the 19th century and the commercial mayhem did not begin until the 20th century.

Are you dressing up for Halloween? What will you be? I am not sure what I will be yet!
